They are commonly found attached to sharks, manta rays, whales, turtles, and dugongs, hence the common names "sharksucker" and "whalesucker". Smaller remoras also fasten onto fish such as tuna and swordfish, and some of the smallest remoras travel in the mouths or gills of large manta rays, ocean sunfish, swordfish and sailfish.
The pilot fish's relationship with sharks is a mutualist one; the pilot fish gains protection from predators, while the shark gains freedom from parasites. [22] It was often said by sailors that sharks and pilot fish share something like a "close companionship"; [ 23 ] there were even tales of this fish following ships which had captured "their ...
As a juvenile, it sometimes acts as a cleaner fish on a reef station; its diet consists of small parasitic crustaceans such as copepods, isopods, and ostracods. [ 10 ] When attached to a host, the remora eats parasitic crustaceans, food scraps from its host's feeding activity, and even some small food captured by filtering water through its ...

Batoid gill slits lie under the pectoral fins on the underside, whereas a shark's are on the sides of the head. Most batoids have a flat, disk-like body, with the exception of the guitarfishes and sawfishes, while most sharks have a spindle-shaped body. Many species of batoid have developed their pectoral fins into broad flat wing-like appendages.
Guitarfish have a body form intermediate between those of sharks and rays. The tail has a typical shark-like form, but in many species, the head has a triangular, or guitar-like shape, rather than the disc-shape formed by fusion with the pectoral fins found in other rays.
The teeth sit outside of the mouth, interlocking, with two large lower fangs that curl upward reaching past the fish’s eyes. Because its jaw can unhinge, the viperfish can eat large prey for its ...
