The male seals dive as deep as 1,430 meters (over 4,600 feet) and stay at depth for up to two hours. “The southern elephant seal is a truly restrained behemoth. Males can grow to be five times larger than females, up to 5,000 pounds. This elephant seal may look...Read more

A beroid ctenophore lunges toward prey with its mouth wide open. Beroid comb jellies don't have tentacles to catch prey: instead, they can open their mouths and snap them shut tight to trap prey inside. And one of their main prey items is other jellies—one species ( Beroe cucumis ) feeds exclusively on them !Read more

In this photo of a shallow coral reef in the Pacific there are three species of forams . On the left, Peneroplis planatus . In the center, Amphistegina lessonii . And on the right, Laevipeneroplis sp. Their colors come from the symbiotic algae that live inside the foram shells. Just like corals, these forams are subject to bleaching when ocean temperatures get high enough to kill off the colorful...Read more

For a long time, scientists thought that some small tentacled fossils were early ancestors of jellyfish. But a new study has found that these ancient animals are actually related to an entirely different group of animals : the entoprocts, which are still alive today. The new fossil ( Cotyledion tylodes ) lived during the Cambrian period (around 520 million years ago), along with the ancestors of...Read more

This swimming crab ( Liocarcinus holsatus ) has a parasitic barnacle rooted in its reproductive system. This invasion cuts off all reproduction for an infected crab and can even cause a male crab to change behavior — males don't normally take care of crab eggs, but the infected male will take care of the barnacle as if it is a brood of eggs.

In 2006, this female giant squid attacked bait suspended beneath a Japanese research vessel off the coast of Japan in the Ogasawara Islands . This screenshot resulted when the research team pulled the 7-meter (24-foot) squid to the surface and videotaped her . It was the first time a giant squid was filmed alive. In 2012, researchers were able to capture video of a living giant squid in its...Read more

The whitish spots on this fish are individual parasitic trematode worms. Trematodes have complicated life cycles that usually involve multiple hosts -- often starting in a snail and then moving on to other hosts, such as fish, birds, and mammals (including humans). They may have even lived in dinosaurs ! Read more about parasites in marine organisms .Read more
