LATEST CATCH

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...

This colony of Rosacea may look like a single jellyfish, but it is actually...

DIVE DEEPER

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...
Seasons in the Ross Sea are marked by ice freezing and melting, and these processes mix the seawater and redistribute salt and nutrients. The influx of nutrients cause phytoplankton to bloom, forming...
These star-shaped grains of sand, collected from southern Japan, look like miniature works of art -- but they were not sculpted by an artist. They are the shells of microscopic organisms called...
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...

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 ,...
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...
Dinoflagellates are an important group of phytoplankton that produce oxygen in marine and freshwater. Some species form symbiotic relationships with larger animals, including corals (zooxanthellae),...
Bull sharks cut a threatening figure with the largest recorded bull shark reaching 11.5 feet and 500 pounds. They prey on dolphins, birds, turtles, bony fish, and other species of shark. Catching...
This foraminifera was collected as it floated about 3 meters below the surface off the coast of Puerto Rico. The central dark area is the shell surrounded by spines. The tiny yellow dots are...

This female hyperiid ( Phronima sedentaria ) is surrounded by her young, residing in the hollowed out barrel-shaped body cavity of a salp. It is thought that the mother Phronima captures and kills...
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...
Scientists describe the amazing bioluminescent creatures they encounter as they descend into the deep--siphonophores, ctenophores, and viperfish--in this Smithsonian/History Channel "Deep Ocean...
This beautiful marine diatom Chaetoceros debilis was caught in the North Sea. Not only are diatoms one of the most important oxygen producers on earth, they are also a vital link in the food chain...
Microscopic, single-celled organisms called foraminifera have a fossil record that extends from today to more than 500 million years ago. Although each foram is just a single cell, they build complex...
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...
