Three distinct types of killer whale, or orcas, can be found in the Antarctic, each with a different habitat and diet preference. One type of orca preys almost exclusively on the Antarctic minke whale, another on seals, and the last eats fish. None have yet been described as separate species, but genetic testing will help scientists know if they should be. See more Antarctic scenes in our Ross...Read more

A colony of 100 million flame shells ( Limaria hians ) was discovered in Scotland in 2012 , and is thought to be the biggest in the world. Flame shells are bivalve mollusks that are shaped a bit like scallops—but they have bright orange tentacles exuding from their shells. Despite their bright color, flame shells are very hard to spot because they hide in self-constructed felt-like nests. They...Read more

Watch as barnacles feed on bioluminescent dinoflagellates. Barnacles are crustaceans (like crabs, shrimps and lobsters) that secrete their shells for protection while living attached to things like rocks, harbors or boat hulls. They feed by reaching their feathery feet out of their shells and grabbing for small plankton. In this video from COSEE Florida and the Ocean Research & Conservation...Read more

Brachiopods are an ancient group of organisms, at least 600 millions years old. They might just look like clams, but they are not even closely related. Instead of being horizontally symmetrical along their hinge, like clams and other bivalves, they are vertically symmetrical, cut down the middle of their shell. While they may all look the same to us, during the Paleozoic era (roughly 250-500...Read more

In the aftermath of the Gulf oil spill, what is the effect of oil on invertebrates like jellyfish, clams, crabs, sea stars, and plankton? The scope of the damage is more easily observed among birds and large animals, but Dr. Chris Mah, an invertebrate zoologist at Smithsonian's National Museum of Natural History, suggests that what we don’t see may be more widespread and devastating. To learn...Read more

Simon Coppard, a post-doctoral research fellow at the Smithsonian Tropical Research Institute in Panama and an Encyclopedia of Life Rubenstein Fellow specializing in echinoids often uncovers new species during his research. In 2006, he and a fellow scientist discovered and described Coelopleurus exquisitus , a previously unknown sea urchin species from New Caledonia in the South Pacific.Read more

The Pacific hagfish ( Eptatretus stoutii ), a fish that looks similar to an eel, has no jaw and is totally blind. They find food, often dead fish, through a specialized sense of smell and, because they can absorb nutrients through their skin, can eat by just burrowing into a dead carcass. However, they also eat live prey. Learn more about their habitat, ecology, and slime-producing habits !Read more

An adult giant squid struggles for survival in an encounter with a sperm whale - its only known predator. The whale will probably overpower and eat the squid. More about the giant squid can be found in our Giant Squid section .Read more

As we dive deeper into winter in the northern hemisphere, the possibility of snow becomes an increasingly frequent topic of conversation. But did you know that the ocean gets a regular dose of ‘marine snow’ year round? The flakes in the ocean are made up of poop from animals, decaying animals and other types of organic matter that slowly make their way to the seafloor—if they aren’t eaten along...Read more
