Arctic Exploration
New technology is making it possible for scientists to go where they’ve never gone before, the depths of the icy Arctic Ocean. By collecting organisms and mapping the seafloor, researchers can discover the effects of climate change on this region and understand the relationship between the ice, water, and the seafloor.

Zombie Worms Eating Whale Bone
Zombie worms (Osedax roseus) eat away at the bones of a dead whale that has fallen to the seafloor in Sagami Bay, Japan. These bizarre worms rely on whale bones for energy and are what scientists call “sexually dimorphic”—the male and female forms are markedly different. In this case, the males are dwarfs that live on the trunks of the female worms.

Deep-Sea Worms
These deep-sea photographs show a variety of broad-collared enteropneusts or acorn worms. These wormlike animals make spiral tracks on the sea floor. All the species shown here are new to science, and most have not yet been collected by scientists. More about deep ocean exploration can be found in the Deep Ocean Exploration section.

Deep-Sea Urchin
This deep-sea urchin (Echinocrepis rostrata) is an important “bulldozer.” It turns over sediment and exposes prey as it moves across the ocean floor, leaving a trail of tracks behind. This photo was taken about 220 kilometers (137 miles) off the California coast and 4,000 meters (13,123 feet) below the surface.

Recliner Rudists
Where ocean currents were strong, ancient rudist “recliners” lay unattached on the seabed. Notice the pink tentacles, which were used to filter feed. Learn more about ocean life throughout deep time in our Ocean Over Time interactive or an image gallery.
