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.

Methanococcus maripaludis is a mesophilic, hydrogenotrophic methanogenic archaeon in the family Methanococcaceae, isolated from salt marsh sediments. It has become an important model organism for studying methanogenesis, archaeal metabolism, and gene regulation due to well-developed genetic tools available for this species. It produces methane by reducing carbon dioxide with hydrogen under strictly anaerobic conditions.
