Sea turtle hatchings emerge from underground nests and crawl across the beach towards the sea. They then maintain an offshore heading until they reach the open sea. [1] The feeding and nesting sites of adult sea turtles are often distantly separated meaning some must migrate hundreds or even thousands of kilometres. [2]
In sea turtles, hatchling sex is determined by incubation temperature. [8] In species in which eggs are laid then buried in sand, indentations in the sand can be a clue to imminent hatching. [ 9 ] In sea turtles, this usually occurs about 60 days after the laying of eggs, and often at night. [ 10 ]
7) Baby sea turtles incubate for 60–80 days and hatch. 8) Newly hatched baby sea turtles emerge from nests and travel from the shore to the water. 9) Baby sea turtles mature in the ocean until they are ready to begin the cycle again. Sea turtles are thought to reach sexual maturity from about 10−20 years old depending on species and ...
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 ...
The most commonly known is the sea turtle. Loggerhead sea turtles are thought to show two different types of homing. The first of which comes in the early stages of life. When first heading out to sea, the animals are carried out by tides and currents with little swimming involved.

About 50% of female sea turtles complete "false crawls," which occur when they crawl onto the beach but return to the water without laying eggs.
[74] [78] Unlike other sea turtles, courtship and mating usually do not take place near the nesting beach, but rather along migration routes between feeding and breeding grounds. [77] Recent evidence indicates ovulation in loggerheads is mating-induced. [79] Through the act of mating, the female ovulates eggs which are fertilized by the male.
