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...
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...
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...
Large whales are notoriously hard to study. Except when rising to breathe, they swim beneath the ocean's surface out of human sight, which makes it difficult to find and track them. They often live...
This new species of lobster is blind—an adaptation to deep-sea life —and has very bizarre claws, or chelipeds. It was discovered about 300 meters (984 feet) deep in the Philippine Sea by a Census of...
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,...
The goblin shark ( Mitsukurina owstoni ) is one of the creepier fish out there! It has a long, prominent snout covered with special sensing organs (ampullae of Lorenzini) that help it to sense...
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...
The yellow features in this 3-D reconstruction of a fin whale fetal skull represent the early developmental stages of ear bones, characteristics that are extremely rare, fragile and nearly impossible...
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...
Sharks have six highly refined senses: smell, hearing, touch, taste, sight, and electromagnetism. These finely honed senses, along with a sleek, torpedo-shaped body, make most sharks highly skilled...
Hear how research unfolds at sea in a tiny Zodiac surrounded by creatures that measure longer than a city bus. Playing female whale calls into the water, researcher Susan Parks suddenly finds herself...
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...
Dr. Stefan Huggenberger from the University of Cologne explains sound production in sperm whales in "Moby Dick's Boom Box: Nasal Complex of Sperm Whales," a presentation at the Smithsonian's National...
Sharks are much older than dinosaurs. Their ancestry dates back more than 400 million years, and they are one of evolution’s greatest success stories. These animals are uniquely adapted to their...
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...
Like other catsharks, the small-spotted catshark ( Scyliorhinus canicula ) is named for the elongated, cat-like shape of its eyes. But all sharks have cat-like eyes—in a different way. Like cats,...
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...
