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 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 (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...
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,...
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...
Hoping to hear bowhead whales , NOAA marine mammal scientist Sue Moore listens to real-time sounds from an underwater hydrophone.
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...
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...
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...
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 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...
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 .
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...
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...
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...
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...
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,...
