Gobies make up the largest family ( Gobiidae ) of fishes in the world, with over 2,000 species. In this large family you can also find the smallest fish. The gobies in this photo are about one inch long (2.5 cm), and most in the family are less than four inches. Because of their small size gobies must work to evade their many predators, often through burrowing or special mutualistic relationships...Read more

Researchers launch one-meter-tall plastic drifters into the Gulf of Mexico in 2012. Over 300 of these drifters were released and their location information was sent to researchers every five minutes through GPS satellite. This project from the Consortium for Advanced Research on Transport of Hydrocarbon in the Environment, or CARTHE, called the Grand LAgrangian Deployment (GLAD) received 5.7...Read more

'Austral' or southern breeders, Great Shearwaters ( Ardenna gravis ) migrate from breeding islands far to the south in the Atlantic before traveling to the Northern Atlantic to feed. This trip is 6,000 miles each way and, if they're lucky, great shearwaters will complete this round trip every year for a 60-year lifetime. See photos and read more about seabird migration .Read more

These beautiful pink and yellow shimmering fish ( Parapriacanthus ransonneti ) live in large groups among corals and in caves where they feed on zooplankton at night. “Golden sweepers form schools in reef crevices and caves and among coral heads. The technique I employed to make this image was a long exposure and rear curtain synchronization combined with a circular rotation of the camera during...Read more

Two fossilized teeth from a megalodon ( Carcharodon megalodon ) dating back more than 20 million years. Their teeth can reach a diagonal length of seven inches! The ancestry of great white sharks has long been debated, but by looking closer at shark teeth scientists know that the giant megatooth shark was not an ancestor of the great white shark. More about the great white shark can be found in...Read more

Grey reef sharks ( Carcharhinus amblyrhynchos ) are among the most versatile and tough predators on a Pacific coral reef, but they are also among the most vulnerable species, as they are threatened by wasteful fishing practices like shark finning . They're also very sensitive to human presence, fleeing reefs when people settle along the coasts and preferring more isolated areas. Where you can...Read more

This foraminifera was collected as it floated about 3 meters below the surface off the coast of Puerto Rico. The central dark area is the shell surrounded by spines. The tiny yellow dots are symbiotic algae, which live in the protoplasm of the host organism. When the foraminifer dies, the spines fall off and only the shell is preserved in the fossil record. Shell building animals like forams will...Read more

The majestic and highly predatory red lionfish ( Pterois volitans ) , native to the Indo-Pacific, is invading Atlantic waters. The lionfish is a popular home aquarium species, and some were most likely dumped off the Florida coast when no longer wanted. The result is a lionfish population explosion that now threatens native species like snapper, grouper, and sea bass. Read " Five Invasive Species...Read more

In November 2012, Australia began protecting a huge swath of its ocean from overfishing and oil exploration, creating the largest network of marine reserves in the world at a grand total of 1.2 million square miles (3.1 million square kilometers). The area, a third of the continent’s territorial waters, includes an underwater canyon as large as the U.S. Grand Canyon, seagrass meadows, and the...Read more

This swimming crab ( Liocarcinus holsatus ) has a parasitic barnacle rooted in its reproductive system. This invasion cuts off all reproduction for an infected crab and can even cause a male crab to change behavior — males don't normally take care of crab eggs, but the infected male will take care of the barnacle as if it is a brood of eggs. Read more about other parasites that you can find in...Read more
