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

These candy cane snapping shrimp ( Alpheus randalli ) have a pretty nice set up. They share their living space with goby fish, helping the fish dig and maintain the burrow that they share in the seafloor. In turn the small, and mostly blind, shrimp (seen in this photo below the goby) get protection from predators in the form of alerts from the goby and a place to call home.Read more

I want snack, so give me cookie! The cookie cutter shark ( Isistius brasiliensis ) is as fearless as they come! This small, 20-inch shark can take on giants like whales and larger sharks, and have even been known to mistakenly try to bite submarines. They dwell in the deep warm ocean and come closer to the surface as the sun sets to grab a quick snack off their unsuspecting prey. Cookie cutter...Read more

The jingle shell ( Anomia simplex ) is a common bivalve found on the Atlantic coast of North America, amongst the more commonly known clams and oysters. As with oysters, the lower shell is glued to a hard surface. Even after the mollusk is dead, the shell keeps its beautiful and shiny exterior. The thin, translucent shells are often used in jewelry, and when strung together can sound like bells,...Read more

This is a tree topper unlike any other! Reminiscent of a freshly made snow angel, these pteropods are actually shell-less sea snails ( Clione limacina ). Unlike the typical snail, they flap their adapted foot ‘wings’ to get around in the water column. They are extremely small, with the largest species reaching only 5 centimeters long. Sea angels' mostly eat their relatives, the sea butterflies ,...Read more

Follow a journey with satellite tags placed on bull sharks and tarpon. Both of these large predatory fish are found in coastal in-shore ecosystems and the two species have similar diets. If given the opportunity, bull sharks will catch and consume tarpon. However, it remains unknown if tarpon adjust their movements to avoid being killed by the sharks. Using the information gained by the satellite...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

One of the smallest shearwaters in the Atlantic, Audubon's Shearwater ( Puffinus lherminieri ) is about the size of an American Robin. They breed on small islands in the Carribbean, and commonly forage around the floating Sargassum endemic to the North Atlantic. Audubon's shearwaters prefer warm, tropical waters, so do not migrate long distances like other shearwaters; however, they are...Read more
