This tiny, shrimplike creature is no more than 2.5 centimeters (1 inch) long, but it’s as ferocious as a shark. Its giant eyes spot prey. Huge claws grab the prey, and a tiny mouth rips it to shreds. The prey never sees what’s coming, because Phronima’s transparent body blends into the surrounding water.

These cancer cells have been treated with discodermolide, a chemical obtained from a sponge that grows on deep-sea coral reefs. It prevents the cells from dividing and spreading.

This hatchetfish was photographed moments after being pulled from the deep sea in the trawling net. These small, silvery fish have large eyes to collect any sunlight that reaches the deep sea. Even in the deep, they are not immune to human impacts; the researchers found many hatchetfish with plastic in their stomachs.

Most lobsters are a mottled brown color, but sometimes you can see a strange orange or blue lobster. And then, when lobsters are cooked, they turn bright red. Why is there such a rainbow of lobster colors? As explained in this video from the American Chemical Society, lobsters eat a red pigment in their plant food called astanxanthin, which helps protect them against stress. This pigment is...Read more

"While Komodo Island, Indonesia is famous for its giant prehistoric lizard, its underwater also holds unique marine species to treasure. The orangutan crab is one of them.

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 open ocean are especially in need of some protection, as they don't have the cracks and crevices that fish in coastal or coral reef habitats have to hide away. Instead, they hide behind one another to...Read more

Charles Viggers/Nature’s Best Photography

“Upon returning from the reef after a night dive, I swam toward a bright reflection and came eye-to-eye with this beautiful, curious squid," said Charles Viggers, a Nature's Best photographer. Squids have organs in their skin called chromatophores that reflect light and can change color to help them blend into their surroundings, attract mates—or attract photographers. They may not be as...Read more

Cooks Bay in Moorea is one of the places that researchers are scouring in their quest to collect one of every life form big enough to pick up with tweezers. In the background is Mt. Rotui—the Tahitian word for octopus. More about the Island of Moorea can be found in our Scientists catalog life on the Island of Moorea featured story .Read more

This ctenophore (a stingless jellyfish-like animal) is native to the east coast of North and South America. In 1982, it was discovered in the Black Sea, where it was transported by ballast water . It subsequently spread to the Caspian Sea. In both places it multiplied and formed immense populations. The sea walnuts contributed to the collapse of local fisheries because they feed on zooplankton...Read more
