Can dolphins breathe underwater? Of all the animals living in the sea, there is one in particular that attracts attention for its intelligence, clever tricks and cute face. That’s right it’s the dolphin! Dolphins spend their lives cruising the depths of the ocean so they must have gills like fish, correct? Actually no: dolphins breathe air like you and I… Their breathing process is a marvel of nature, a testament to their adaptation to aquatic life. They use blowholes on top of their heads to breathe, a process that is voluntary and conscious. Despite their aquatic lifestyle, these mammals need…

We are talking about the little fellas of the Ocean – the nudibranch. These tiny ocean dwellers are sometimes difficult to spot because of their size. Often they are just the size of a fingernail. For many experienced divers, finding one during a dive and being able to photograph it is something special. Many divers have no idea what they are and pass them by. These little colorful friends are creatures with truly special features. Let’s start by defining what they are. Nudibranchs are a group of soft-bodied marine gastropod molluscs, belonging to the order of Nudibranchia. They shed their…

Yes, it is often possible to distinguish between male and female fish. General clues include body shape, fin shape, and the presence of specific markings like egg spots. For example, males might have more vibrant colors and slimmer bodies compared to females, and their anal fins may be more pointed. With manta rays and sharks, it is pretty easy to tell, as we can see their external sex organs. Females have a cloaca and males claspers. General differences: Body Shape: males tend to be slimmer and more torpedo-shaped, while females are often more rounded. Fin Shape: Male anal fins…

Smart fish are able to recognise each other, navigate a maze, escape predators, fall in love, hunt together – let’s have a closer look what else smart fish can do. Do fish: Get Thirsty Fish don’t get thirsty in the way we do but they do need water. Freshwater fish constantly draw water into their bodies due to the higher salt concentration inside their cells compared to the surrounding water. They do that through their skin and gills. Saltwater fish lose water through their skin & gills. They need to drink seawater to balance their internal fluids and maintain proper…

Over half of the world’s coral reefs have disappeared since the 1950s, and in Australia alone, nearly 50% of the Great Barrier Reef’s coral died in just two heatwaves. But where destruction leaves a void, innovation dares to fill it to save coral reefs. Off Australia’s coast, scientists are turning to an unlikely hero: 3D printers. With ceramic blocks designed like underwater Lego, they’re building homes for fish, one interlocking piece at a time. And the wildest part? The ocean is responding. Fish are already moving in. Coral is beginning to regrow. Nature is adapting to what humanity has created—this…
