Plastic-Degrading Enzymes May Be Increasing in Response to Pollution

One in every four organisms in the microbiomes they surveyed carries a plastic-degrading protein sequence

In the video, Wheaton, a veterinarian, and his board appear tiny compared to the colossal bony fish. While the sunfish's dimensions are unknown, when comparing it to Wheaton's 14 foot-long board, the sunfish may have been anywhere between nine to ten feet long. (Pictured: Matt Wheaton)

The unprecedented feeding plan comes as more than 1,000 manatees—about 15 percent of the state’s total population—have died this year

A squid swims in the dark waters of the Mediterranean. Billions of aquatic animals, from krill to squid, travel to surface waters each night, a migration that scientists are only beginning to fully grasp.

What Drives Aquatic Animals to Make Vertical Migrations?

Researchers are trying to shed light on what leads many water dwellers—from plankton to large fish—to commute daily from the depths to the surface
