Baja California Sur, Mexico

“Born during the great mobula aggregations of spring, juvenile Munk's devil rays remain in the Sea of Cortez long after their parents have left, using the shallow bays of Espiritu Santo Island as a nursery,” explains Spiers. “By autumn, the water is clear, a bonus for underwater photography but also signifying less food for the filter-feeding rays. At night we hung a green light from the back of our boat, as plankton gathered around it the mobula rays gratefully swooped in for a microscopic buffet. The rays seem to fly through the water as they pursue their dinner. Entranced by their grace, I used a two-second exposure to capture their movements which, to my eye, felt like an aquatic ballet.”

Tahiti, French Polynesia

“This image of a mother and calf humpback whale was shot off Tahiti where these whales migrate to from Antarctica to mate and give birth,” explains Capozzola. “I was privileged to swim with these beautiful creatures which almost became extinct in the 1980s. As I waited on the surface for the whales to ascend nearby, these two then rose directly underneath me through the sun’s bright rays, creating a heavenly scene. Normally, I shoot my camera upwards, but here I shot downwards to capture the sun’s rays contrasting through the water and illustrate the respective sizes of mother and calf.”

British Columbia, Canada

Baby plainfin midshipman fish, still attached to their yolk sacs in British Columbia, Canada. “They are guarded over by their father until they are big enough to swim out from under the rock they are living on in the intertidal zone and swim to ocean depths,” explains Gross.

The Bahamas

A scuba diver looks tiny swimming in front of a shipwreck. “We were on a liveaboard cruise to take underwater images of tiger and hammerhead sharks in the Bahamas,” remembers Friedrich. “But due to bad weather conditions, we had to seek shelter near Nassau where we looked for alternate dive sites. We decided to dive on this wreck which had been intentionally sunk by a dive centre. At that time, the sand under the bow was washed out which made it an excellent photographic opportunity.”

Seychelles

Peppered moray eels look for food in a tidal pool at low tide on D’Arros Island in the Seychelles. “Their ability to come completely out of the water is amazing and surprising,” says Gross. “D’Arros Island and St. Joseph Atoll are now a Marine Protected Area (MPA) which gives me hope. MPAs may be our best tool for the long-term health of our ocean.”

Tahiti, French Polynesia

A close-up shot of a nurse shark’s eye. “The shark was resting under some coral when I approached. Seeing that it wasn't bothered by my presence, I tried to find a less common photographic point of view,” explains Anton. “I really loved the eye contact and the graphic aspect of this shark’s skin. The monochrome aspect of the image gives the scene more intensity.”

Philippines

A coconut octopus sits inside a plastic sandwich bag. “These octopuses typically hide inside empty shells or coconut shells,” explains Formis. “This time, the octopus chose what was available instead - plastic packaging. Unfortunately, it's completely transparent, making the octopus easily visible. It was a sad and touching behavior to witness at the same time.”

Thailand

“The hingebeak shrimp is typically seen in colonies, and this one, nestled in the hollow of a barrel sponge, is the largest I’ve encountered,” remembers Chonecadeedumrongkul. “These striking shrimp, with vivid red and white stripes, display dance-like movement, swaying back and forth with their beaks pointed upwards. I observed this lively group just before dusk. One shrimp in the foreground appeared to lead the others like a maestro guiding an orchestra. In underwater photography, we often seek rare sights and unique scenes, sometimes overlooking the common ones, yet this performance reminded me of nature’s wonders and extraordinary beauty.”

Baja California Sur, Mexico

A triumphant mahi-mahi or common dolphinfish proudly displays its catch amidst a feeding frenzy. “Its vibrant yellow and green hues shimmer brilliantly under the refracted sunlight against the stunning blue of the Pacific Ocean,” says Castellanos Raboso. “The bait ball was semi-static, allowing us to spend some time in the water with these fish, moving like torpedoes in front of us. This scene captures the essence of the hunt and the energy of Baja's marine life, witnessed yearly in what has become one of my favorite places on Earth.”

Isle of Noss, Shetland Islands

A northern gannet dives into the water to catch its prey. With a 180-centimeter wingspan, they are one of the largest seabirds in British waters. “Whilst their size alone is impressive, what makes this bird remarkable is its ability to plunge-dive at high speeds,” says Hoksbergen. “I wanted to capture the beauty of this incredible feat: the moment a northern gannet plunges into the sea, like a bullet piercing through the calm surface of the sea. Northern gannets have a number of adaptations that make it a true ‘ocean bird’. These adaptations enable them to dive from heights of 30 meters, hitting the water at speeds of up to 60 mph.”

Hawaii, USA

Freedivers from the Papahānaumokuākea Marine Debris Project work to remove a large ghost net from the waters of the extremely remote, uninhabited Pearl and Hermes Atoll. “This image was taken late in the field season, and I love the way the black and white brings out the hard lines and perseverance in their faces,” explains Sullivan-Haskins. “At this point, the team had been working for nearly two months straight and removed almost 200,000 pounds of ghost nets from this Marine Protected Area. This is grit, this is determination, this is conservation in action.”

Canada

An orca exhales on the surface. “I was camping in the Broughton Archipelago in Canada and was exploring the area for the day with our small RIB boat. On the evening cruise back to camp, I suddenly spotted some blows in the distance. I shut down the engine and sat in awed silence,” remembers Williams. “Time slowed down and as the light drew in, I felt my other senses were heightened. With no other humans around for many miles, it felt as though we could have been part of the pod ourselves. The killer whales’ exhales echoed off the nearby cliffs as they moved slowly in our direction. Their underwater vocalizations could at times be even heard above the surface.”

Costa Rica

A whale shark swims alongside the Sharkwater research vessel, a ship that was initially used by the Japanese fishing fleet and is now used for research. “I was on a shark tagging expedition with Fins Attached, CREMA, and Pelagios Kakunjá aboard the Sharkwater,” explains Herreño Parra. “When we got back from one of our dives, the crew spotted a friendly whale shark. We jumped in to install an acoustic tag, took tissue samples, and measured the individual, while I was documenting everything. After the researchers went back on the boat, I stayed in the water with the shark for almost an hour, trying to take an image of the endangered species below the scientific vessel. It all came together, and the moody light and the rough sea add to the image’s special appeal.”

Lembeh, Indonesia

A patch of clownfish eggs. “They were taken care of by their parents,” explains Friedrich. “After taking a few shots of the clownfish pushing some water onto the eggs, I decided to go for a close-up shot of the eggs which were sticking out pretty nicely on the small rock.”

Raja Ampat, Indonesia

A healthy coral reef in one of the most biodiverse places in the world. “On our last dive of a two-week trip to Misool Eco Resort in Raja Ampat, our crew took us to Tank Rock, a small dive site near the resort,” says Peterson. “On that afternoon, there were an astounding number of fish in the shallows with fusiliers, anthias, snapper, soldier fish, banner fish, and more all swimming together in their respective schools. Current was running high, so all the corals were open and the soft, fading light was just right to capture the beauty of a healthy ecosystem in action. The Misool area in particular is an excellent example of preservation at work. The efforts of the local people to protect the ocean is unprecedented and the results of their labors are evidenced in this photograph."

Baja California Sur, Mexico

A fever of mobula rays stirs up the seabed. “Mobula rays are incredibly sensitive to movement and sound,” explains Tepsaskul. “Opportunities to swim with them like this are rare and is definitely a once-in-a-lifetime experience for me. After about half an hour of swimming with these beautiful creatures, they quietly disappeared into the big blue. It was like being in a dream.”

Antarctica

A colossal iceberg in Antarctica. “We were exploring the Weddell Sea for the first time, venturing as far as the unforgiving ice allowed,” remembers Markov. “One morning, while on deck, I gazed in awe at the colossal icebergs drifting by. Suddenly, I noticed something hanging on the side of one iceberg. Through my binoculars, I spotted Adélie penguins clinging to the ice. It was incredible. These penguins often use icebergs for protection or rest, but braving such a steep, towering iceberg was a testament to their resilience and determination. The ice wall's shapes were breathtaking - a stunning masterpiece crafted by Mother Nature herself.”

Iceland

“This image was shot at night time, in the world-famous Silfra fissure in Iceland, a tectonic boundary between the North American and Eurasian plates,” explains Conroy. “You get underwater visibility of 100 meters or more here. This was a difficult photo to shoot as the water temperature was 1 degree Celsius, while the air temperature was in the minus range. We used artificial light at night for a new perspective of the rift.”

Isle of Noss, Shetland

An entangled gannet hangs off a cliff. “No words are needed to tell this gannet’s story - perhaps that’s what makes it so powerful,” says Douglas. “Its story ruptured something inside me when I saw the devastation. The swell was high, the gannet was spiralling around and as the boat moved away and its profile came into view, I captured this shot. My eyes followed the rope, revealing nests full of plastic. I wanted to make the bird’s life count with this image so it didn’t die in vain. Its confronting story and its legacy highlights the impact humans have on wildlife.”

Israel

A mesmerizing spectacle beneath the waves: Like clockwork, thousands of corals spanning hundreds of kilometers synchronize their efforts to reproduce, releasing egg and sperm bundles into the open sea. “Capturing coral spawning is no small feat, demanding precision and patience as it unfolds fleetingly, occurring once a year, on a specific night of a particular month, and within a narrow time window of mere minutes,” explains Shlesinger. “This image stands as a testament to an ongoing scientific documentary journey, where the vibrant nightlife and intricate reproductive rituals of corals and other reef dwellers in the northern Red Sea unfold. I dedicated over 300 nights to unveiling the secrets of the corals’ major reproduction season. To immortalize the underwater spectacle, I used a slow shutter speed, transforming the coral spawning into an ethereal display akin to an underwater fireworks show.”

Anilao, Philippines

A poison ocellate octopus or motor on a pyrosome, a pelagic colony of tunicates. “The poison ocellate octopus shares the same potent toxins with its relative, the blue ring octopus,” explains Lu. “Captured during a blackwater night dive, this juvenile octopus measured about 2 centimeters. Each night during the vertical migration, deep-sea creatures like this octopus migrate upwards to the lighter, shallower waters to feed and avoid predators before descending back into the depths by morning. Pyrosomes often serve as resting spots or transportation for these ocean travelers.”

Norway

A whale-watching trip boat encounters a dead sperm whale off Andenes in Norway. “While sad, its demise allowed researchers on the boat to gather data and opportunistic samples to learn from its loss,” adds O’Callaghan. “Measurement data is crucial for my PhD, so I sent the drone up to record the dead animal. One of the captains, Luis, moved into the shot with his boat to show the whale’s scale against a 12-metre-long boat. It really was a trip to remember.”

Hon Yen, Vietnam

“While photographing the shallow coral reefs along the coastline of Hon Yen, Phu Yen province in Vietnam, I noticed a long trail of smoke coming up from a local fishing boat operating not far from the coast,” says Nguyen Ngoc. “I decided to fly my drone to take a look and coincidentally took this image from above. It shows the soft light of a new day, illuminating the long trail of smoke from the boat’s chimney, while it perfectly aligns with the shape of the green nets moving under the surface. Many local fishing families along this coastline will follow the near-shore currents to catch anchovies during peak season. Salted anchovy is the most important raw material to create traditional fish sauce - the spirit of Vietnamese cuisine."

New South Wales, Australia

A surfer rides a large wave, while a bright rainbow forms behind it. “He looks like he's having the best time of his life,” says Bachellereau. “In this image, the clear blue water is showing off the natural beauty of the ocean. This picture captures the joy and excitement of surfing, highlighting the special bond between the surfer and the sea in a moment of pure happiness.”

Philippines

A freediver amidst a shoal of sardines. “As a freediver and photographer, I'm always mesmerized by the dance of sardines,” explains Yavar. “On this dive, I found myself beneath a swirling ring of sardines, forming a perfect circle above me. The sunlight piercing through the water created a stunning contrast, highlighting the intricate patterns of the fish and the diver. It felt like every movement was in perfect harmony. Capturing this moment was a blend of luck and timing. This shot captures the harmony between human and marine life, showcasing the serene beauty of the underwater world.”

Mentawai Islands, Indonesia

"The Mentawai Islands are home to some of the best waves on the planet. It’s also home to breathtaking landscapes where jungle fights for real estate right up to the ocean’s edge," says Barton. "For surfers, this juncture is where we obsessively spend most of our time (or would like to). To document the full beauty of these scenes, I often pull back the focal length, inviting the viewer to experience the full majesty of these coastal zones while simultaneously capturing the high-speed action of the sport I love. I shot this one in black and white to emphasize the contrast of the elements as the sun illuminates the subject while the background is in shadow."

San Diego, California

A California moray eel pauses at the surface of its rapidly shrinking world. “The intertidal world is an ever-changing landscape,” says Jacobs. “On an early morning expedition to a pool I’ve gone to for years, I found an exciting find. A young California moray, a species rarely found in our intertidal. I spent the blue hour and the transition to dawn with this eel, framing the shot with its reflection, showing the ephemeral nature of its fleeting pool.”

The Bahamas

Scientists conduct an ultrasound on a female tiger shark off the coast of Grand Bahama. “She was discovered to be pregnant, and a groundbreaking device called a birth tag was inserted into her uterus which does not harm the mother or pups,” explains Houppermans. “When the shark gives birth, the tag will be expelled with the pups. It then signals to a satellite, alerting the scientists to the time and location of the birth. Once the birth tag was in place, the shark was measured, the hooks removed, and she was quickly released unharmed.”

The Bahamas

“Freediver Sun Young Kim dives in the ‘no fins’ category at Vertical Blue 2021, a freediving competition, in the famous Dean’s Blue Hole in the Bahamas,” explains Verhoeven. “For years I’ve tried to get all the elements - the diver, the comp zone, the action, and the underwater sand falls - into one image. This was the first time it all came together.”

Mentawai Islands, Indonesia

A surfer duck-dives his board under a large wave over a shallow reef break. "My aim for this session was to capture photos of surfers inside the barreling part of the wave as they raced past me," explains Barton. "Given the dynamic nature of swimming in the surf, I’m always looking for unique angles and compositions. During this session, a large set wave caught me out of position, forcing me to swim to the reef to avoid getting sucked over by the turbulence. This particular moment gifted me this unique perspective that I feel is both serene and chaotic at the same time."

Japan

A diver swims through the whimsical waters off Iwo Jima. “Iwo Jima is a volcanic island with hot springs. When the water from the hot springs flows into the sea, the shallower the water is, the more red or orange it turns,” explains Kurashima. “The visible colors in the water vary depending on the concentration of the hot spring's components, and the appearance is compared to an aurora borealis. The diver swimming in front of me had a very good posture, which made for a good silhouette.”

Western Australia

A group of swimmers enjoys crystal-clear waters. “Our fascination and connection to the ocean mean more and more sports are practiced in the water,” says Tommasi. “The turquoise waters of Southwest Australia are the perfect background for swimming and other watersports, providing not only a source of physical exercise but also mental health and connection with nature. Viewed from the air, the swimmers turn into little specks of colour in the immensity of the ocean.”

Portugal

A pregnant stingray is trapped in an aquaculture frame. “Currently, about 40% of the world's fish is caught accidentally and is dead or dying when returned to the sea. There is an urgent need to implement methods that significantly reduce bycatch,” explains Rodrigues. “For fishing to be sustainable, it is not enough to safeguard the stock of a certain species. It is equally important to think of all those who will be sacrificed in vain. Fortunately, this trapped stingray survived. After a successful rescue carried out by the tuna farm divers, she swam away to give her one more day of hope.”

The Maldives

Marine biologist Kaia Ali tends to the coral restoration project at COMO Cocoa. “The Maldives, the flattest country in the world with an average altitude of only just above 1 meter, deserves praise for the efforts it has made to conserve its ocean patrimony,” says Spiers. “Industrial fishing with nets is banned and the country created one of the world’s first national shark sanctuaries. However, the Maldives have suffered greatly at the hands of environmental changes which transcend their borders and strong El Niño events have killed 80 to 90% of all the shallow hard corals. Hope for the future lies in part with efforts to regrow the reef through coral gardening. I visited these structures and can only cross my fingers that they can be part of the solution.”

Norway

“The storm raged all night with howling winds, the temperature far below zero,” remembers Ochs. “By morning, it was suddenly quiet. I set out for the beach, trudging through the deep snow, and breathing in the freezing air. As I arrived at the lineup, the fog lifted, revealing perfect little longboard waves against a majestic mountain backdrop. I swam out, and light snow began to fall, adding to the surreal beauty. Very few surfers in thick neoprene suits braved the icy waters, their faces beaming with joy. In the solitude of this breathtaking landscape, I was rewarded with the opportunity to capture this unforgettable encounter with nature's raw beauty.”

Nusa Lembongan, Indonesia

Seaweed farmers in Indonesia. “The locals begin work each day at sunrise. Cultivating and harvesting seaweed is tough work, but offers a source of income, along with a chance to regenerate the diverse ecosystems within the area,” says Nirandara.

Svalbard, Norway

The Bamsebu whaling station in Svalbard. “I have visited Bamsebu a few times before, and each visit brings an eerie feeling. This old whaling station, where hunters exclusively targeted belugas, still bears their bones scattered along the shores. We bring guests here to reflect on the horrors of the past and the possibility of change. With beluga whaling now banned in Svalbard, we can only hope their numbers will rise again. In this image, I aimed to capture the haunting atmosphere and the harsh conditions in which the whalers once lived.”

Portugal

After being trapped in a fishing net for several hours, this injured leatherback turtle was rescued from the waters of the Algarve. Rodrigues explains: “The 300 kg male was transferred to the Marine Species Rehabilitation Centre at Zoomarine's Porto d'Abrigo, where he spent 49 days in quarantine to recover. Upon release, a satellite tag was fixed to its carapace to collect data on the turtle's future journey. Monitoring was scheduled for three years but was interrupted after only 21 days. Even so, the collected data was enough to intrigue the investigators. From the moment it was released back into the ocean in the Algarve, the leatherback turtle swam an impressive distance of 1,000 kilometers, until it reached reaching Fuerteventura, in the Canaries. According to biologist Élio Vicente, the coincidence of being in an area of ​​intense maritime traffic could be one of the explanations for the release of the tag.”

Java, Indonesia

Shark fins dry on a roof. “During an assignment documenting shark and ray fisheries in Java with the Mobula Project Indonesia and the Manta Trust, I was invited to a shark processing unit nestled between market stalls and homes, where shark fins are dried,” remembers Corbett. “The high demand for shark fins in Asian medicine, combined with declining fish stocks, forces many fishers to target these vulnerable species for their livelihoods. Learning about the low pay, long hours, and harsh conditions faced by these fishers was heartbreaking. They are often vilified for their work, driven by depleting fish stocks and a flawed economic system. Understanding the broader context and addressing the issue at all levels is crucial.”

Indonesia

A critically endangered smoothnose wedge fish demonstrates the cost of bycatch. “I had the privilege of joining fishers as part of the ‘Kebersamaan Untuk Lautan’ NGO project in Sumatra. During my time on the water, I witnessed the retrieval of hundreds of meters of gillnets, revealing a shocking amount of shark and ray bycatch,” explains Page. “From the depths emerged a creature rarely seen by divers, the critically endangered smoothnose wedgefish. As it was hoisted towards the boat, I was given seconds to capture the shot and document a powerful image in the fight to save this critically endangered species from extinction.”

Barents Sea, Arctic

A melting ice shelf in the Arctic creates waterfalls. “The shelf extends for hundreds of kilometers along the high Arctic landscape. The jagged edges show the sheer magnitude of ice protruding into the ocean,” says Portelli. “As temperatures increase, the rate of glacial melt increases, causing dramatic raging waterfalls to drain into the ocean. The impacts will be felt almost immediately for life in the Arctic.”

Mayotte

A bleached coral reef. “This image was taken close to the site where I photographed the image of a thriving coral reef that won third place in the Conservation (Hope) category last year,” says Barathieu. “This photo unfortunately shows the reef during an episode of stress and bleaching in 2024. The contrast between the two images is striking. A loss of color, biodiversity, and biomass is evident. I hope that coral mortality won't be too high and that there won't be another bleaching episode in the coming years.”

Seychelles

Juvenile rays rest in the shallows of the St Joseph Atoll Marine Protected Area. “This corner is only accessible during specific tides,” explains Pouponeau. “We surveyed mangroves for research with the Save Our Seas Foundation – D’Arros Research Centre when we came across this special sight. Although the rays always thrive in the Atoll, their congregation varies with different conditions. Capturing them requires ideal tides, stagnant waters, and good visibility. Here, everything came together, and the image portrays the importance of healthy mangrove habitats and isolated island sanctuaries.”
