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 .

[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 ...
The common remora (Remora remora) is a pelagic marine fish [3] belonging to the family Echeneidae.The dorsal fin, which has 22 to 26 soft rays, acts as a suction cup, creating a vacuum [4] to allow the fish to attach to larger marine animals, such as whales, dolphins, sharks, and sea turtles.
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 ...

In fish anatomy and turtle anatomy, a barbel is a slender, whiskerlike sensory organ near the mouth (sometimes called whiskers or tendrils). Fish that have barbels include the catfish , the carp , the goatfish , the hagfish , the sturgeon , the zebrafish , the black dragonfish and some species of shark such as the sawshark .
Deep-sea chimaera photographed by the NOAAS Okeanos Explorer.Visible on its snout are tiny pores which lead to electroreceptor cells.. Chimaeras are soft-bodied, shark-like fish with bulky heads and long, tapered tails; measured from the tail, they can grow up to 150 cm (4.9 ft) in length.
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.
