From Coral Reefs To Deep Sea Creatures: 30 Stunning Underwater Photographs By Daniel Sly

Bored Panda wanted to dive deeper into the fascinating work of the photographer, so we reached out to him and asked a few questions. Daniel kindly shared with us how some of his shots have completely changed the way he sees the ocean and certain marine species. Here’s what we found out: “Diving with great white sharks off the southern coast of Australia completely changed the way I see them. Most images we see of great whites show them at the surface, where they typically take their prey, often in dramatic, high-energy moments. But at depth, it’s a completely different experience. They’re calm, curious, and undeniably intelligent, each shark with its own unique personality. 

Even though I already understood the importance of these apex predators in the ecosystem, seeing them firsthand confirmed it on a whole new level. There’s a presence to them that’s hard to describe until you’re in the water with them, watching how they move, how they observe you, and how different they are from the mindless hunters they’re often made out to be. Capturing those moments where they’re not lunging or breaching but simply existing in their environment felt important. It’s one thing to have in your mind that sharks aren’t the villains they’re often portrayed as, but another to witness it, camera in hand, and try to share that perspective with others.”

We were curious if, in any situation, Sly managed to form a connection with a particular marine animal while photographing it. The photographer explained that by diving in the same local sites over months and years, he has come to recognize individual marine creatures and watch their lives unfold. He elaborated: “Seahorses especially tend to stick to the same sponge or coral patch dive after dive, while certain anglerfish shift territories but remain within a familiar range. Even well-camouflaged creatures like pygmy pipehorses become recognisable with time, whether through unique markings, injuries, or subtle differences in shape and colour. There’s something special about returning to a dive site and spotting a familiar face, like a seahorse that’s grown noticeably rounder with pregnancy or an anglerfish that’s shifted to a new hiding spot.

Following the same individuals over time makes me appreciate how much change happens in the underwater world. Some creatures disappear, new ones arrive, and behaviours shift with the seasons. It turns photography into more than just capturing a moment; it becomes a way of witnessing and documenting their lives as they unfold.”

Daniel also shared with us some interesting facts about underwater photography that some people might not be aware of: “Most people don’t realise just how much patience and precision underwater photography requires, not just in capturing the shot but in understanding marine life behaviour. It’s not just about finding something interesting and snapping a photo; you need to anticipate movements, adapt to constantly changing lighting, and control your buoyancy with extreme precision. Small disturbances, like a misplaced fin kick, can ruin both visibility and the moment.

Another surprising aspect is that some of the best shots come from the most unexpected places. What might look like a dull patch of sand or a piece of debris can actually be home to fascinating marine life. Underwater photography is as much about revealing hidden stories as it is about taking beautiful pictures.”

Our final question focused on Daniel’s work in relation to how people perceive marine life and ocean conservation. The photographer told us: “The phrase ‘you don’t care about what you don’t know’ really applies to marine life and ocean conservation. If people aren’t aware of what’s beneath the surface, they’re less likely to care about protecting it. Sharing images makes these creatures real to them; it’s one thing to hear about habitat loss, but another to see a photo of a seahorse clinging to broken, dying coral or a fish making a home inside discarded plastic.

One of the most rewarding aspects of underwater photography is seeing how it changes the way non-divers perceive marine life, especially here in Sydney. A lot of people don’t realise just how much biodiversity exists right off our coast. Many assume you have to go to the tropics to see anything interesting. But when they see a photo of something like a weedy sea dragon, a tiny pygmy pipehorse, or even a well-camouflaged anglerfish, their reaction is often pure surprise: ‘That’s here?!’ It highlights how little the public knows about what’s in our own backyard, and it becomes clear that showcasing these creatures is key to sparking interest and care for ocean conservation.”
