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

No iguana wants to be cooked alive on a hot rock and then served up as dinner for a Galapagos hawk. But it turns out the marine iguanas ( Amblyrhynchus cristatus ) have a strategy that warns them of...
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...
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...
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...
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 .
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 "...
