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.

Haladaptatus paucihalophilus is a halophilic archaeon within the family Halobacteriaceae, notable for its ability to tolerate a relatively wide range of salt concentrations compared to most extreme halophiles. It was isolated from a low-salt, sulfide-rich spring and represents an unusual adaptation among haloarchaea. Its name reflects its capacity to thrive in environments with lower halide concentrations.
