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.
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 ...
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 ...
In fish anatomy and turtle anatomy, a barbel is a slender, whiskerlike sensory organ near the mouth. 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 .
Colors depend on the species, ranging from pink to blue-grey, and black or white spots may be present. Eyes are simple eyespots, not lensed eyes that can resolve images. Hagfish have no true fins and have six or eight barbels around the mouth and a single nostril.
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.
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.
They host sharks, rays, and sea turtles [71] [circular reference] and eat food scraps, ectoparasites, [71] and possibly the feces of their host. [70] Juvenile Golden trevally are occasionally sold as Pilot fish.
