Great white sharks ( Carcharodon carcharias ) are marvels of evolution, with highly-evolved senses keeping them among the ocean’s top predators. However, they are threatened with extinction and...
Researchers from the SOCAL-10 research partnership study the behavior of orcas (commonly called killer whales) and how they react to sonar and other noisy human activities. The partnership is...
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,...
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 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...

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...
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...
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...
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...
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...
Check out the eyes on these Hawaiian squirrelfish ( Sargocentron xantherythrum )! Because squirrelfish are almost entirely nocturnal, they need big eyes to absorb as much moonlight and starlight as...
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...
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...
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...
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...
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 .
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...
