The live sharksucker (Echeneis naucrates) 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.^[1] The species stays close to coral reefs and feeds primarily off hosts, such as sting rays, sharks, sea turtles, dolphins, whales and also ships.^[1] The live sharksucker feeds off of both the host's prey and its parasites.^[1] The species has been known to attach itself to divers' legs in attempt to create a host creature on which to feed.^[1] 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.^[2] This does not hurt the host.^[2] Sharksuckers benefit from their host by saving energy through not needing to move around, which is why they have been vulgarly named "hitch-hikers".^[2] They do this because they lack the essential swim bladder to be able to manoeuvre comfortably.^[2] 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.^[2]
