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.

Sphacelaria tribuloides is a small, tufted brown alga forming compact cushion-like colonies on rocky substrates and larger algae. It inhabits intertidal and shallow subtidal rocky zones in temperate and tropical seas worldwide. This photosynthetic alga reproduces via characteristic star-shaped propagules and colonizes rocky marine surfaces.
