Like other sea snakes , the turtle-headed sea snake ( Emydocephalus annulatus ) has fangs and venom. But its venom is weak so, instead of defending with a bite, the species tends to react to danger by swimming back to a crack or crevice to hide. For food, the sea snake sneaks around coral reefs looking for fish eggs attached to coral or rocks. It then uses a large tooth-like scale on each side of...Read more

Starksia blennies, small fish with elongated bodies, generally native to shallow to moderately deep rock and coral reefs in the western Atlantic and eastern Pacific oceans, have been well-studied for more than 100 years. It would have been reasonable to assume that there was little about the group left to discover. Using modern genetic analysis combined with traditional examination of morphology...Read more

The blue crab ( Callinectes sapidus ) is one of the most important commercial species in the United States, especially in the Chesapeake Bay region on the Mid-Atlantic coast. Its populations are affected by local water quality, overfishing, reproduction dynamics and bycatch amounts, and efforts to protect the region and crab species have been ongoing. Parasites can also affect the commercial...Read more

What is blue carbon? It's a term used to describe the carbon that is captured from the atmosphere by ocean ecosystems, mainly coastal mangroves, seagrasses and salt marshes. These coastal areas can hold up to five times more carbon than tropical forests , which means they play an important role in both removing excess carbon from the atmosphere and storing that carbon for the long haul...Read more

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 small comb jelly snares prey with its two short tentacles. Read m ore about the deep sea and comb jellies .Read more

A parent Magellanic penguin ( Spheniscus magellanicus ) sits with its big chick. Magellanic penguins live in South America, breeding in colonies along the coasts of Chile, Argentina and the Falkland Islands, and some migrate north to Brazil. Parents typically lay two eggs under a bush or in a burrow, taking turns swimming out to sea to catch food for their chicks. But the largest colony in the...Read more

There is a huge amount of plastic trash floating in the ocean, which endangers wildlife that eats or gets tangled in it. Reducing the amount of plastic trash in the ocean doesn't seem that hard; people just need to use less plastic, such as packaging, drinking straws and plastic bags. But it can be very hard to break people's habits. In 2002, Ireland made a simple change: they started charging a...Read more

Sponges are animals that eat tiny food particles as they pump water through their bodies. They are very common on Caribbean coral reefs, and come in all shapes, sizes and colors. There is great variability in their size: some sponges are very small (just a few centimeters) while others are very big, like the giant barrel sponge, which can be six feet wide. Even sponges of the same species can...Read more
