Sea turtle migration is the long-distance movements of sea turtles (superfamily Chelonioidea) notably the long-distance movement of adults to their breeding beaches, but also the offshore migration of hatchings. Sea turtle hatchings emerge from underground nests and crawl across the beach towards the sea.
Among the reptiles, adult sea turtles migrate long distances to breed, as do some amphibians. Hatchling sea turtles, too, emerge from underground nests, crawl down to the water, and swim offshore to reach the open sea.

Sea turtles: there are seven extant species of sea turtles, which live mostly along the tropical and subtropical coastlines, though some do migrate long distances and have been known to travel as far north as Scandinavia. Sea turtles are largely solitary animals, though some do form large, though often loosely connected groups during nesting ...
Turtles can detect all Earth-strength magnetic fields, ranging from around 25,000 nanoteslas to 65,000 nanoteslas — a measure of magnetic field intensity, according to Goforth.. To understand ...
Animals that use sun compass orientation are fish, birds, sea-turtles, butterflies, bees, sandhoppers, reptiles, and ants. [15] When sandhoppers (such as Talitrus saltator) are taken up a beach, they easily find their way back down to the sea. It has been shown that this is not simply by moving downhill or towards the sight or sound of the sea.
In contrast to their earth-bound relatives, tortoises, sea turtles do not have the ability to retract their heads into their shells. Their plastron, which is the bony plate making up the underside of a turtle or tortoise's shell, is comparably more reduced from other turtle species and is connected to the top part of the shell by ligaments without a hinge separating the pectoral and abdominal ...
Sea turtles are a charismatic megafauna and are used as symbols of the marine environment and environmentalism. [3] As a result of its role as a slow, peaceful creature in culture, the turtle can be misconceived as a sedentary animal; however, many types of turtle, especially sea turtles, frequently migrate over large distances in oceans.

Kemp's ridley is the smallest of all sea turtle species, reaching maturity at 58–70 cm (23–28 in) carapace length and weighing only 36–45 kg (79–99 lb). [13] Typical of sea turtles, it has a dorsoventrally depressed body with specially adapted flipper-like front limbs and a beak.
