Hydra viridissima is a species of cnidarian which is commonly found in still or slow-moving freshwater[2] in the Northern temperate zone. Hydra viridissima is commonly called green hydra due to its coloration, which is due to the symbiotic green algae Chlorella vulgaris which live within its body.[3] These creatures are typically 10 mm long and have tentacles that are about half of their length.[4] They are strictly carnivorous and typically feed on small crustaceans, insects and annelids. Hydra are normally sessile and live on aquatic vegetation. They secrete mucous to attach to substrate using their basal disc.[4]
