An Atlantic puffin ( Fratercula arctica ) carries many sandlances ( Ammodytidae ) in its mouth to take back to its hungry chick. Puffins have spiny tongues that, pressed against the roof of their...
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...
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...
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-...
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...
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.
Polar bears have evolved to survive in the Arctic with large, oar-like front paws for better swimming, as well as insulating blubber, and two layers of fur for the frigid temperatures. They rely on...
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...
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...
Sharks have young in three different ways. After internal fertilization, some species lay a thick egg case that encloses the shark embryo (seen in the photo here). Most species are ovoviviparous,...
Like this ctenophore ( Aulococtena acuminata ), many animals that live in the midwater zone are red—making them almost invisible in the dim blue light that filters down from the sea surface. This...
This aptly named fish ( Anoplogaster cornuta ) has long, menacing fangs, but the adult fish is small, reaching only about 6 inches (17 cm) in length. It's teeth are the largest in the ocean in...
Rivulus fish live in bodies of water that sometimes become contaminated with hydrogen sulfide—an extremely toxic compound that smells like rotten eggs. When this happens, the adaptable fish wiggle...
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...
Several species of amphipod like this one, Gammarus wilkitzkii , live permanently within Arctic sea ice . These animals are endemic, meaning they only live here. They acclimate to a wide range of...
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...
This jelly’s red color provides camouflage in the deep ocean. Red light rarely reaches those depths, and most deep-sea animals have lost the ability to see red. The long, complex tentacles of this...
