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...
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," says one fish in this video. The world of drifters is the world of zooplankton...
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...
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...
Scypholanceola aestiva looks like an armored alien of the deep. It doesn’t have compound eyes like other hyperiids, but instead sees variations in light using reflective cups embedded in the...
Hyperiid amphipods are small crustaceans related to sand fleas and distantly related to shrimp. They range in size from very tiny to more than 7 inches long, and are found at all depths of the ocean...
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...
This colony of Rosacea may look like a single jellyfish, but it is actually a large group of smaller siphonophores clustered and living together. In fact, the zooids (individual siphonophores living...
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...
This is another view of Phromina from the side. The eyes take up most of the head, with one pair looking to the side (the red spot) and one pair facing upwards. Phronima live anywhere from 200-1100...
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...
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...
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...
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 ,...
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),...
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...
