The Echeneis naucrates or live sharksucker is a rare species of remora, from the family Echeneidae. The species generally occurs in all tropical seas around the world, mainly in warm waters. The species stays close to coral reefs and feeds primarily off hosts, such as sting rays, sharks, sea turtles, dolphins, whales and also ships. The live sharksucker feeds off of both the host's prey and its parasites. The species has been known to attach itself to divers' legs in attempt to create a host creature on which to feed. Echeneis naucrates has a disc feature on the top of its head which enables it to attach itself to its hosts without losing its grip. This does not hurt the host. Sharksuckers benefit from their host by saving energy through not needing to move around, which is why they have been vulgarly named "hitch-hikers". They do this because they lack the essential swim bladder to be able to manoeuvre comfortably. Echeneis naucrates has been of use to fisherman who would attach a line to the animal and set them into the water to find a host and then haul it in.
