Researchers have identified the first known case of a crocodile making herself pregnant — and producing a fetus that was genetically identical to herself. The findings were published Wednesday by a team led by evolutionary biologist Warren Booth from Virginia Tech in Biology Letters, a journal published by the Royal Society.
In 2018, officials with the Parque Reptilandia in Costa Rica found 14 eggs in a female's enclosure. The crocodile had been in isolation since the age of 2, yet she still managed to lay a clutch of eggs at 18.
"Given the period of isolation from mates, these would normally be considered non-viable and discarded," the researchers wrote. But the officials gathered seven eggs that appeared viable and kept them in an incubator.
