What is a sea turtles size and coloration?
This depends on what type of sea turtle you're talking about. Green sea turtles reach about 78 to 112 cm (31-44 in.) and 68 to 186 kg (150-410 lb.), while leatherbacks reach about 1.2 to 1.9 m (3.9-6.2 ft.) and 200 to 506 kg (441-1,116 lb.).
Green Sea Turtles have green flesh. The shell is olive brown to black, while the skin is pale yellow to creamy white. The shell has many different colors. Very rarely will you find a green sea turtle with a solid colored skin. The leatherback turtle is darkly-colored, with white and pink spots.
they camaflage them selves by putting there head in there shell and waite. This is completely wrong. Sea turtles' shells are fused in such a way that it does not allow them to pull their heads or limbs inside their shells at all. Box turtles, other land tortoises, and aquatic turtles have the ability to pull their limbs inside, but sea turtles do not. They CAMOUFLAGE themselves with the coloration of their shells blending in…
When sea turtles are young they really have no defenses against prey. They're only chance of survival is to find a bed of floating algae to hide themselves in and feed on until they make it to other sea turtle populations. Sea turtles usually travel in fairly large groups keeping them safe and have quite an intimidatingly large size at adulthood.
