Green Sea Turtle

The green sea turtle is one of the largest sea turtles. They are named for the green color of their cartilage and fat, not their shells.

Hemiselmis anomala is a unicellular cryptomonad alga found in marine and estuarine environments, characterised by its asymmetric, kidney-shaped cell and two unequal flagella for swimming. It contains phycobilin pigments allowing photosynthesis and plays a role in marine and coastal primary production. Cryptomonads like this species are significant contributors to phytoplankton communities in diverse aquatic habitats.
