what are doese small things that are always under sharks?

Question

They look like fish

Answer 1

They are fish called remoras!

Remoras or suckerfish are elongate brown fish in order Perciformes and family Echeneidae.[1][2] They grow up to 30-90 cm long (1-3 feet), and their distinctive dorsal fin takes the form of a modified oval sucker-like organ with slat-like structures that open and close to create suction and take a firm hold against the skin of larger marine animals. By sliding backward, the remora can increase the suction, or it can release itself by swimming forward. Remoras sometimes attach themselves to small boats. They also swim well on their own, with a sinuous motion.

Remoras are primarily tropical open-ocean dwellers, occasionally found in temperate or coastal waters if they have attached to large fish that have wandered into these areas. In the mid-Atlantic, spawning usually takes place in June and July; in the Mediterranean, in August and September. The sucking disc begins to show when the young fish are about 1 cm long. When the remora reaches about 3 cm, the disc is fully formed and the remora is then able to hitch a ride. The remora's lower jaw projects beyond the upper, and there is no swim bladder.

Some remoras associate primarily with specific host species. Remoras are commonly found attached to sharks, manta rays, whales and turtles, (hence the common names sharksucker, whalesucker). Smaller remoras also fasten onto fish like tuna and swordfish, and some small remoras travel in the mouths or gills of large manta rays, ocean sunfish, swordfish, and sailfish.

The relationship between remoras and their hosts is most often taken to be one of commensalism, specifically phoresy. The host they attach to for transport gains nothing from the relationship, but also loses little. The remora benefits by using the host as transport and protection and also feeds on materials dropped by the host. There is some controversy over whether a remora's diet is primarily leftover fragments, or actually the feces of the host. In some species (Echeneis naucrates and E. neucratoides) consumption of host feces is strongly indicated in gut dissections.[3] For other species, such as those found in a host's mouth, scavenging of leftovers is more likely. Many sources also suggest that for some remora/host pairings the relationship is closer to mutualism with the remora cleaning bacteria and other parasites from the host.

Answer 2

Some sharks have parasitic fish that attach themselves to the shark. I can't remember the biological term, but they help each other. The remora (parasitic fish) will clean the shark, while it feeds on left-over scraps of whatever the shark has just killed.

Answer 3

Pilot fish.
they attend the sharks and whenever the shark gets a parasite the pilot fish eat the parasites off the shark. Also the pilot fish lead the shark to food.

Answer 4

One of the things under sharks is called a sucker fish, they are waiting for the shark to attack and not swallow all of its catch.

Answer 5

Food scraps. Sharks aren't the tidiest eaters.
