Imagine if a fish at the market could tell you where it came from; what would it say? "I came from a world of drifters,"...
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...
This much smaller hyperiid (in the genus Paraphromina ) has eyes that make up 45 percent of its body! Its many retinas, which researchers believe are used to maximize light detection, are the small...
This hyperiid (in the genus Cystisoma) has only one pair of eyes—but they are very big. You can see them here as the entire surface of its head and the convex orange sheet of retinal cells in the...
These Themisto hyperiids live in the top 200 meters of cold waters around the world. Each of their two large eyes has an upward-looking zone and a downward-looking zone. Each zone can see at...

The ocean is home to a phenomenal diversity of marine organisms. They have evolved to inhabit warm waters near the equator and the icy waters of the Earth’s poles. Marine life takes advantage of the...
Scientists use a multinet to collect Arctic zooplankton samples from different depth layers in the water column .
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 ,...
How do you explain a scientific paper in three minutes or less? What if you were being judged by a bunch of middle-schoolers in classrooms around the world… and you only had a month to do it? The...
Now that the Census of Marine Life is over, we’re checking in with some of its researchers to hear about their favorite expeditions, what they learned, and how the Census and its findings continue to...
