Loggerhead sea turtle laying her eggs on a beach in Bahia

Описание: There are seven species of Sea Turtles in the world: the Green Sea Turtle (Chelonia mydas), the Loggerhead Sea Turtle (Caretta caretta), the Hawksbill Sea Turtle (Eretmochelys imbricata), the Leatherback Sea Turtle (Dermochelys coriacea), the Olive Ridley Sea Turtle (Lepidochelys olivacea), the Kemp's Ridley Sea Turtle (Lepidochelys kempii), and the Flatback Sea Turtle (Natator depressus).
When they hatch, sea turtles crawl to the ocean, where the survivors spend the rest of their lives. Males never go back to land, but females have to so that they can nest. They find their way back to the same beach where they hatched, decades later, then crawl up the beach, usually when it is dark, and when they find the perfect spot, the digging begins. It can take a whole hour to dig a nest, then lay the eggs, cover it up, and make sure nobody finds it because that is all the parental care they are going to get: making sure the eggs are as safe as possible before the mother goes back to the ocean. It is truly impressive how they can dig such a perfect nest, having only flippers. They slowly scoop the sand out with one hind flipper, throw it away, then make sure there's no sand left on the other flipper before putting that one down in the hole to repeat the process.
