Hantkenina mexicana -- a foram with elongated shell chambers that lived between 45-49 million years ago, during the Eocene Epoch. This specimen is from marine sediments that were drilled in the...
This image from a scanning electron micrograph magnifies the tiny teeth that cover the surface of the giant squid’s tongue-like organ, or radula . Seven rows of sharp teeth help direct tiny pieces of...
Lenticulina secans -- this foram lives on the seafloor. This specimen was collected from ocean sediments in southeast Tanzania. It comes from a time over 92 million years ago when both the polar...
Any floating object in the ocean tends to attract life; fishermen know this and deploy floating buoys to concentrate fish for harvesting. Plastic marine debris is no different and, at microscopic...
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...
The ocean is so big that it can be easy to forget the microscopic beauty of the organisms that live within. Some of this beauty is documented by the Nikon Small World photomicrography competition ,...
This photograph from a scanning electron micrograph shows the plastisphere up close. Here you can see a microbial reef forming on a tiny piece of plastic found in the open ocean. A variety of single-...
This hyperiid is one of twenty-four species in the genus Vibilia , distinguished by the paddle-like antennae on the front of its head. Vibilia are small (only 5-20 millimeters long) and their eyes...
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...
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 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...
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...
Ichthyologist John R. Paxton of the Australian Museum studies freshly caught lanternfishes. Paxton was on the team that solved the whalefish mystery .
Coral sand is aptly named: it's sand made up of tiny bits of coral and other ocean animals such as foraminifera , molluscs, and crustaceans. This image, taken at 100x zoom, took 18th place in the...
This hyperiid is one of seventeen species in the genus Lanceola , which are found between 200 and 7,000 meters below the ocean’s surface. Some species, like this one, are found exclusively below 3,...
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...
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...
Unlike the green, leafy algae we're used to seeing on the seafloor, coralline algae has a hard crust—which you can see here at the molecular level in a photo from a scanning electron microscope. Each...
