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.

Hapalosiphon luteolus is a filamentous, branching cyanobacterium found in freshwater habitats, damp soil, and moist terrestrial environments including peat bogs and wetland margins. It produces a yellowish pigmentation and forms heterocysts capable of nitrogen fixation. This species contributes to nitrogen cycling in wetland and semi-aquatic ecosystems where it forms part of benthic microbial communities.
