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.

Surirella biseriata is a large, boat-shaped freshwater diatom with two rows of fibulae forming a distinctive pattern along both sides of the valve. It inhabits benthic zones of clean to moderately enriched freshwater lakes and rivers across temperate regions. This photosynthetic diatom contributes to benthic algal communities and organic matter production.
