Can you spot the amphipod (Phronima atlantica) in the below photo? She's the transparent lobster-looking animal in the middle, surrounded by her own eggs -- inside a sac that once was the "barrel" of a salp. Mothers in the genus Phromina attack the barrel-shaped salps, hollowing out the inside...

This copepod (Gaussia princeps) was collected deeper than 1000 meters in the Sargasso Sea by Census of Marine Zooplankton (CMarZ) researchers in April 2006, as part of the 10-year Census of Marine Life. However, specimens of this species have been collected in all the world's oceans at many depths...

Holozooplankton (hereafter called "zooplankton") are small animals that drift in the ocean waves through their entire lives. As such, they are not very easy to count or even identify to species -- but that was the goal of CMarZ. The scientists working on the project aimed to study the species...

This copepod Calanus hyperboreus (up to 7mm in length) lives in the Arctic, usually within 500 meters of the surface. To survive the cold Arctic winters, Calanus hyperboreus builds up dense fat (lipid) supplies on its body, which makes it a preferred food of both...

In the icy waters of the Arctic, a deep-water larvacean (aka “sea tadpole” because it looks like a tadpole) drifts through the water in its 'house.' This house is made of protein and creates almost a shell around the larvacean and helps to filter particles out of the water for the larvacean to eat...

For being so big, right whales eat very small food, which they catch using baleen. Baleen is the series of fringed plates hanging in right whales' mouths that are used to strain seawater for food. Until the early 1900's, right whales were heavily hunted primarily for their fatty blubber, which...

Found in Arctic waters, this rare deep-water species of larvacean, Oikopleura gorskyi, eats by filtering particles from the seawater it drifts through. Larvaceans build 'houses' around themselves made of protein that helps them filter the water even better. And when the filters in its house...

In many species of copepods, males are rare and short-lived. This male of Scaphocalanus acrocephalus is readily distinguished from the female by features of his antennae and tail. View the “Under Arctic Ice” photo essay to learn more.

Holozooplankton are animals that live adrift in the ocean waves for their entire lives. The researchers who took part in the Census of Marine Zooplankton, a project of the Census of Marine Life, spent a decade surveying and photographing holozooplankton biodiversity around the world. Here is a...

This magnified photo provides a close-up look at copepods—tiny crustaceans that right whales feed on. There are many species of copepods that live throughout the water column, from floating at the surface to buried at the bottom of the sea. They are very small so right whales need to eat a lot of...

The comb jelly (ctenophore) Thalassocalyce inconstans is found in shallow to deep water in the Atlantic Ocean, Mediterranean Sea, and sometimes in warmer Pacific Ocean waters off the coast of California -- although this one was photographed in the Sargasso Sea by Census of Marine Zooplankton...
