The whalesucker (Remora australis) is a species of remora in the family Echeneidae, so named because it attaches itself exclusively to cetaceans, in a mutualistic interaction. It is found worldwide in tropical and warm waters; in the Gulf of Mexico and western Atlantic Ocean, it occurs from Texas to Brazil, and in the eastern Pacific Ocean, it occurs from Vancouver Island to Chile. It is the rarest member of the remora family, though this may reflect more the uncommon collection of cetaceans in the wild rather than the whalesucker's actual abundance.
