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 .
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...
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...
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...
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...
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 goblin shark ( Mistukurina 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...
The distinctive form of a winghead shark ( Eusphyra blochii ) is revealed by an X-ray image. The Winghead Shark, one of about ten species of hammerhead sharks, has its eyes set at the tips of its...
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...
Hoping to hear bowhead whales , NOAA marine mammal scientist Sue Moore listens to real-time sounds from an underwater hydrophone.
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 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...
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...
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 "...
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,...
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.
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...
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...
