Image of the Day: The Hidden Rainbow of an Arctic Worm
Alexander Semenov photographed a colorful Alitta virens deep underwater in the arctic. He is a researcher and photographer at the remote White Sea Biological Station. Alitta virens—also known as “sandworms”—are commonly used as live bait by commercial fishermen. In addition to their brightly colored bodies, these amazing creatures can also reach up to 4 feet in length. However, their abundance is greatly threatened by overharvesting.
