Yikes! That's a #bloodworm.🐛 A carnivorous member of the Annelida phylum -- they feed by extending a large proboscis, bearing four hollow jaws, and utilize venom to kill their prey. Reproduction occurs in midsummer, as the warmer water and the lunar cycle triggers sexually mature worms to transform into a non-feeding stage called the epitoke. The worms swim to the surface of the water where both sexes release gametes, and then die. FIN. #Science | Science Channel
