Tank is a Hermann's Tortoise and he's about 4 months old. He has a brother who's even teenier and tinier than he is. He was left to the U.K.'s Paradise Wildlife Park by their former head of reptiles as a leaving present.
Hermann's Tortoises live across Southern Europe, although their once expansive range has been reduced to scattered pockets. Abundant as pets in captivity, this species is in significant decline in the wild due to habitat destruction.
