Myths and legends

And there are many versions. To separate the wheat from the chaff, you need to understand where the name came from. What is a pilot? Fish in fact was so named casually. In marine terminology, this word means a boatmaster who is familiar with the underwater terrain and is able to plot a course. Most likely, the name of this fish is due to one of the most important misconceptions, which says: a fish pilot accompanies a visually impaired shark, helping to find food and avoid dangers. For this, they say, the shark and allows its little striped escort to pick up the crumbs from her royal table.fish pilot and shark

There is another version. According to her, the pilot eats shark feces or parasites attached to her skin.

Perhaps the shark is only for protection? This version has neither proof nor refutation. The shark does not rush to protect the pilots, and it is unlikely that anyone will be able to attack the satellites of a dangerous predator. But this assumption also raises one question: why does not the shark try to regale pilots? After all, this fish is edible, tasty and quite comparable to other prey that makes up the diet of sharks.

And the pilot - a fish, which is often confused withstuck. A lot is known about the relationship between the prilipala and the shark. Of course, they can not be called parasitism, because they do not cause harm to the shark. But the fact that one fish simply lives at the expense of the second, does not cause disputes. She can not even walk. Pilots are not riders, they just float nearby.

Scientific versions

Although science does not know for certain thatconnects sharks and fish-pilots, but scientists know for sure what exactly is not and can not be. The version of navigational functions is untenable, if only because sharks are simply enviable sight, and smell is even better, they are perfectly oriented even in troubled waters.

Version of eating scraps (and even more soparasites and feces) is even more unfounded. The stomachs of the pilots were examined more than once, and for a long time scientists have observed their behavior. Cruising alongside the shark, pilots periodically pick up a zazyvavshuyusya fishes or crustaceans and eat them.

Even scientists have established that if a shark engages the enemy or becomes a prey of hunters, the striped train leaves it instantly, and then proceeds to search for a new patroness.

Other strange friends

Pilot - a fish that "friends" not only with the mosta dangerous predator of the ocean. Often, divers find it in the company of huge turtles, rays, other large marine inhabitants.

But so far they have much more questions than answers.
