On this signal, the female places around 250 eggs into his pouch. These ruby red eggs take eight weeks to hatch and when the young leave they are on their own. Unfortunately this leads to a low survival rate of...Read more

The spanish dancer is not just known for its dance. It has a...Read more

Bull sharks cut a threatening figure with the largest recorded bull shark reaching 11.5 feet and 500 pounds. They prey on dolphins, birds, turtles, bony fish, and other species of shark. Catching such a wide array of prey is possible because bull sharks can survive in both coastal freshwater and saltwater. However it was still a surprise for some golfers in Australia that these versatile sharks...Read more

The whale shark ( Rhincodon typus ) is the largest fish on Earth. They spend most of their lives in the deep water up to 200 meters or more, but swim up to the surface to gather food and warm their bodies. In Kwatisore—located in Cenderawasih Bay National Park, Papua, Indonesia—they interact with bagans ( fishing platforms on the water's surface ), which provide ikan puri (anchovy), a staple in...Read more

Lying on the ice with a few friends is not an unusual way to spend time for walruses, who tend to be sociable animals. Their groups can range from tens to thousands. Each individual herd has a dominant male who is established by his aggressiveness, tusk size and physical size. Though due to the competitiveness for dominance, the social structure always remains on thin ice.Read more

Frogfish are skilled hunters and some species are capable of blending into local environments such as coral reefs . A frogfish can camouflage itself so well that prey fish will swim close by without seeing the predator lurking before them. Then, before the prey knows it, he’s eaten in about 6 milliseconds! The frogfish is an eating machine with a mouth cavity that can grow up to 12 times its size...Read more

Anemone porcelain crabs may look delicate but they have their own sort of armor: a hard exoskeleton. They live under rocks, sponges, groups of feather stars, and even in giant anemones where they can hide inside the tentacles. Once inside they do not have to worry about gathering food since they are mainly filter feeders . Anemone porcelain crabs are also masters of escape and, if attacked, can...Read more
