The two-headed red slider turtle has turned up at a reptile centre in Pennsylvania, where owners are amazed by its freak appearance.

The unnamed curiosity has two heads on opposite sides of a single shell, as well as six legs and a combined tail.

A collector in Fort Lauderdale, Florida, passed the freak of nature to Big Al’s Aquarium Supercenter in East Norriton.

Jay Jacobi, the shop’s exotic reptile manager, said: "The two heads seem to have their own thoughts, operating independently."
