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.
