Hyperiid amphipods are small crustaceans related to sand fleas and distantly related to shrimp. They range in size from very tiny to more than 7 inches long, and are found at all depths of the ocean...
About 100 million years ago , during the heyday of the dinosaurs, reefs were built by mollusks called rudist clams. Like modern clams, rudists were bivalves , with two shells (or valves) joined at a...
It may be the last place you’d expect to find corals—up to 6,000 m (20,000 ft) below the ocean’s surface, where the water is icy cold and the light dim or absent. Yet believe it or not, lush coral...
This bait ball shows how small fish can react when larger predators are near by gathering tightly together in a ball-like formation that exposes the least number of fish. Fish species found in the...
Deep sea animals have to live in a very cold, dark, and high-pressure environment where they can't see a thing! To survive there, they've evolved some very strange adapations. Some make their own...
This lizardfish ( Bathysaurus ferox ) rests on the ocean bottom with its head slightly elevated—waiting to snatch prey with its large mouth and sharp teeth. It lives at depths of 600-3,500 meters (1,...
A thresher shark’s long tail fin helps not only its swimming ability, but also its ability to hunt. It can use the fin to herd and trap schooling fish by swimming in increasingly smaller circles...
Even on an early winter morning, it was sunny and warm in southern Florida. This was great because, regardless of the weather, Dr. Jon Norenburg and I were going to walk chest-deep into the water to...
These beautiful mandarinfish ( Synchiropus splendidus ) are covered in bright blue, red, yellow and orange waves. What they lack, however, are traditional fish scales. They live in western Pacific...
Giant squid live up to their name: the largest giant squid ever recorded by scientists was almost 43 feet (13 meters) long, and may have weighed nearly a ton. You’d think such a huge animal would be...
Scientists know the Greenland shark ( Somniosus microcephalus ) moves slowly in the Arctic's cold water. They also know that parasites attack the shark's eyes. But much about this animal remains a...
With gnarled teeth and a perpetual frown, the sea wolf is a creature out of our nightmares! But despite its fearsome look, it isn't a danger to humans, largely preying on whelks, crabs, and sea...
Adaptation is the key word if you are looking to survive in a tide pool, a space that some scientists describe as the most competitive real estate in the ocean. Tide pools are exposed to the water's...
Weddell seals grind their teeth on holes in the ice to keep them open to their comings and goings between ocean and air. Their dives can last over an hour when they are looking for an opening in the...
Hidden beneath Arctic ice is a world few have ever seen. Take the icy plunge with a team of ice-loving scientists.
Like many deep sea creatures, this tiny comb jelly ( Bathocyroe fosteri ) has a transparent body, enabling it to blend into the surrounding waters. This ctenophore is very common around the Mid-...
A smasher mantis shrimp came out from its burrow on a fringing reef adjacent to the USS Liberty ship wreck in Tulamben, Bali, Indonesia at a depth of 6 meters. The smashers use their raptorial claw...
