Ships are well-known for their tiny rooms and tight quarters. But have you heard of a sea vessel that has toilets and sinks sticking out of the walls, and staircases and doors on the ceiling? This...
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 blue-spotted stingray ( Taeniura lymma ) doesn’t like to be covered in sand like other species of stingray do. Instead, it prefers to show off its beautiful blue spots and, to stay up to the best...
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...
A great white shark ( Carcharodon carcharias ) emerges from the water's surface, gaping at the photographer. Gaping is a way sharks communicate with each other, and maybe even try and communicate...
Giant squid have the largest eye in the animal kingdom. At up to 10 inches in diameter, people often describe it as the size of a dinner plate -- or, in other words, as big as a human head. Here,...
A mantis shrimp ( Odontodactylus scyllarus ) holds her clutch of eggs in her clubbed claws. Usually these claws are weapons that punch hard-shelled prey at speeds of more than 50 miles an hour...
Under white light, this shortnose greeneye fish ( Chlorophthalmus agassizi ) looks unimpressive. But, in dim blue light—the type usually seen at depth—it shows its true fluorescent colors. NOAA...
What does a bioluminescent creature that lives more than two miles below the surface of the ocean and a glow stick have in common? More than you think. In a unique spin on an art technique called "...
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...
The Pacific hagfish ( Eptatretus stoutii ), a fish that looks similar to an eel, has no jaw and is totally blind. They find food, often dead fish, through a specialized sense of smell and, because...
Polarized sunglasses have become the norm for humans when they want to filter out the strong glare from the sunlight bouncing off of water in a horizontal direction. But how do animals do that live...
John Hildebrand discusses his research at the Scripps Whale Acoustic Lab on the FLIP platform. Learn more about how scientists are using bioacoustics to study and protect whales .
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...
Animals, on land and in the ocean, live in a 3-D world, and they depend on their sense organs and brains to build the mental constructs that allow them to orient and navigate, which is crucial for...
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...
Researchers from the SOCAL-10 research partnership study the behavior of orcas (commonly called killer whales) and how they react to sonar. Read more in a blog post from one of the researchers.
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...
