Today's Catch

For two months, Cassandra Brooks , a marine scientist with Stanford University, travelled on an ice-breaking ship through the Ross Sea in the Antarctica—and she filmed the whole thing. A camera hooked to the front of the ship recorded the ship’s travels, and the ever-changing sea ice. Sea ice isn’t just a solid layer covering the water’s surface. Sometimes the ice looks like shining glass...Read more

There are 47 different species of seahorses and 14 of those were discovered in the last eight years, including Pontoh's pygmy seahorse ( Hippocampus pontohi ), which was officially named in 2008. Seahorses’ ability to change their color and shape to blend in with their environment makes identification of individual species challenging. Because of this, some researchers previously thought there...Read more

When it comes to many of our once-favorite seafoods, there aren't always plenty more fish in the sea. In fact, some studies estimate that up to 90 percent of large predatory fish (those that eat other animals—and usually end up on our dinner plates) have disappeared since humans began heavy fishing. You can help turn the tide by demanding sustainable seafood at the supermarket and in your...Read more

These cute Adélie penguins ( Pygoscelis adeliae ) are actually having a bit of a spat. In the spring (October for them), the penguins form breeding colonies on rocky coasts with thousands of birds in a group. Krill, a tiny crustacean, is the penguins' main food source, but krill populations are being affected by climate change and the Adélie penguin populations are decreasing as a result. “This...Read more

Check out the eyes on these Hawaiian squirrelfish ( Sargocentron xantherythrum )! Because squirrelfish are almost entirely nocturnal, they need big eyes to absorb as much moonlight and starlight as they can in the dark. During the day, they hide out in the nooks and crannies of tropical coral reefs. To defend its small hiding place, the squirrelfish grunts by grinding its teeth and stretching the...Read more

Gray reef sharks ( Carcharhinus amblyrhynchos ) are known for being active at night. They are considered Near Threatened by the IUCN Red List due to fishing and the loss of their coral reef habitat. The sinister animal, with its sleek body, can be quite aggressive when directly threatened. “It was shaping up to be a bad night dive when my mask broke and I was forced to come up early. The others...Read more

Tectitethya crypta (formerly known as Cryptotheca crypta ) is a large, shallow-water sponge found in the Caribbean. It was first studied for medical purposes in the 1950s when few scientists or doctors thought to look for medicines in the ocean. But in the sponge, scientists isolated two chemicals — aptly named spongothymidine and spongouridine — which were used as models for the development of a...Read more

This sea potato ( Echinocardium cordatum ) looks similar to its root vegetable namesake, but it's a sea urchin! The spines on this urchin are more hair-like than the spikes seen on some more commonly known urchins, and they lay flat across the urchin's body. They can be found buried in the sediments of the sea floor. In their burrow they separate themselves from the sand and mud with a layer of...Read more
