Description: A remora, also called a sharksucker, has a strange suction disc that looks like a Venetian blind on its head. The disc allows the remora to cling to sharks, bony fishes, sea turtles, marine mammals. The remora gets free transportation and feeds on ectoparasites and “leftover” scraps from the host.
