Just like other seahorse species, male weedy sea dragons are the ones to get 'pregnant' and give birth to the babies. To show he is ready to hold eggs, the male wrinkles part of his tail. On this signal, the female places around 250 eggs onto a brood patch that has small cup-like indentations, like a sponge. These ruby red eggs take eight weeks to hatch and when the young leave they are on their...Read more

When the spanish dancer swims, the wide edges of its mantle (the parapodia) are pushed through the water in a graceful undulating movement reminiscent of flamenco dancers. The spanish dancer is not just known for its dance. It has a...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

The frogfish is an eating machine with a mouth cavity that can grow up to 12 times its size...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

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

Like its terrestrial namesake, the Venus fly-trap anemone ( Actinoscyphia sp.) sits quietly and waits for food to drift into its outstretched tentacles, which are lined with stinging harpoons called nematocysts. Of course, this is how most anemones behave; this one just happens to look a like like the Venus fly-trap plant! They are deep-sea animals; this one was photographed at roughly 4,900 feet...Read more
