The basic body plans of all modern animals were set during the Cambrian Period, 542 - 488 million years ago. Your friends, family, and pet turtle may not look much like the creatures here. But we and...
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...
This red octopod ( Stauroteuthis syrtensis ) shines in a novel way. Suckers stretching in a single row down each arm flash on and off. The glowing-sucker octopod drifts through deep waters off the...
Bioluminescence is one of the more captivating adaptations that have evolved in marine animals. It's the ability of organisms to create and emit light. Dive underwater and you may witness lightshows...
A huge colony of brittlestars (likely Ophiacantha rosea ) covers the peak of a seamount in the deep ocean. What’s the attraction? Food! Their arms reach out for tiny food particles carried by the...
Great White Sharks are stealthy hunters and the secret is in their skin. Shark skin is covered by tiny flat V-shaped scales, called dermal denticles, that are more like teeth than fish scales. These...
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...
Arctic cod have a special protein that keeps their blood from freezing in ice-cold Arctic waters.
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,...
At the Poles, Life Thrives Located beside the Shores and Shallows gallery (which highlights different kinds of coastal ecosystems around the world), the Poles area will take you to the ends of the...
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...
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...
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...
This crab ( Neolithodes sp. ) was collected on a NOAA/MAR-ECO cruise to the Mid-Atlantic Ridge in the summer of 2009. Its red color provides camouflage and protection from predators. Red wavelengths...
This shadowy fish, Trematomus bernacchii , is well adapted to the ice-cold water of the Antarctic: its blood comes equipped with natural antifreeze. This is a necessary adaptation because the...
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...
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...
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,...
