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.

Rhodomonas abbreviata is a photosynthetic cryptophyte flagellate in the family Pyrenomonadaceae, characterized by its small, compressed cell with two unequal flagella and distinctive phycoerythrin pigments that give it a reddish coloration. It inhabits marine and brackish coastal waters where it contributes to nanophytoplankton communities. Cryptophytes like this species are important food sources for zooplankton and heterotrophic protists.
