Did you know that over 17,000 species thrive in the deep sea where no light penetrates the ocean waves? Or that an old...
The Census of Marine Life was a ten-year effort by scientists from around the world to answer the age-old question, “What lives in the sea?” The international effort to asses the diversity,...
A fringe of short tentacles surrounds the flattened bell of this tiny, transparent jellyfish ( Halicreas minimum ), which can be found at depths up to 984 feet (300 meters). But it would be hard to...
Like this ctenophore ( Aulococtena acuminata ), many animals that live in the midwater zone are red—making them almost invisible in the dim blue light that filters down from the sea surface. This...
Sea stars ( Odontaster validus ) and sea urchins ( Sterechinus neumayeri ) spread over an algae-covered seafloor off the coast of Antarctica. These two species are often found living in association...
This new species of deep-water sea cucumber ( Elpidia belyaevi ) was discovered by Census of Marine Life researchers in the frigid waters of the Arctic . Since the 1800s, researchers observed sea...
Many expeditions in the Arctic reveal new species, such as this jellyfi sh Bathykorus bouilloni , which, strangely, has only four tentacles! Dr. Kevin Raskoff from California State University,...

This jelly’s red color provides camouflage in the deep ocean. Red light rarely reaches those depths, and most deep-sea animals have lost the ability to see red. The long, complex tentacles of this...
Expedition data went to the Arctic Ocean Diversity database of the Census of Marine Life to establish a baseline that will help to document change in the poorly known Arctic Ocean. Scientist Kevin...
Scientists believe orange roughy ( Hoplostethus atlanticus ) live longer than 150 years! Here, Census of Marine Life researchers used an underwater camera to photograph this group of orange roughy...
