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 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...
Scientists use a multinet to collect Arctic zooplankton samples from different depth layers in the water column .
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...
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...
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),...
You may have seen the sparkle of fireflies on a summer’s night. The fireflies produce light through a chemical reaction in their glowing abdomens, a process known as bioluminescence. But did you know...
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...
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...

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...
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...
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...
