coral reefs of the Red Sea, Indian and Pacific oceans - it's surprisingly diverse world, but our understanding of the processes that affect it, is rather limited.
example, just able to establish that the fish involved in cleaning, have a tremendous impact on many aspects of life in this environment.In addition, they are a vivid example of mutually beneficial symbiosis.What is and what "profession" has a fish-cleaner, you will learn on.
What does Cleaner
body of any fish eventually becomes home to a variety of parasites that feed on blood, mucus, or waste products of the owner.Land animals are known to be plagued by the same problems, but they have paws, teeth, noses and claws, they can help themselves or fellow pack.A fish does not have such opportunities, and here to help them come "sea Doctor" - a small fish-cleaner.
It is small (no more than 14 cm).And it is justified, because it falls during processing to climb into the mouth and gill slits even jaded parasites "patients."The latter, incidentally, goes in search of themselves "doctors" are blue and yellow fish in the open coral reefs where cleaners organize something like a point of "first aid".
How does the "cabinet" cleaning
What makes fish-cleaner, you can understand, observing how it operates "Cabinet".The reefs can often find a queue of different species of marine life, waiting patiently for opportunities to get such help they need.Sometimes, of course, as well as in human clinics, where there may be an argument for the right of the first to be cleaned, but, mostly, fish decorously waiting in the wings.
Interestingly, at that time, declared that even a sort of truce.That is predatory moray eels can easily be close to their potential victims, without showing the slightest interest in them.
What are fish cleaners
most common fish cleaner - is representative of the family Wrasse (the so-called wrasse)."Profession" wrasses are obliged to form their mouths, similar tubes and armed special design of the teeth, looks like a pair of tweezers, which allows them to most effectively explore every centimeter of the body "of the patient."
two fish species from this family: Thalassoma lunare and Thalassoma amblycephalum - incredibly sociable by nature, often operate large flock, like a swarm of bees.They are surrounded by, for example, a huge, floating lazily above them slope and enjoy the meeting not less than it.For here there is a mutually beneficial cooperation: the ramp turns into a huge dining table for fish, receiving in turn, clean body and, consequently, health.
Doctor's "profession" fish-cleaning
Cleaners absolutely insatiable.It checked that they can "accept" the day about 300 fish, carefully picking their unwanted tenants.Do not forget at the same time and on the balance between food teeth huge fellow.Furthermore, they devour algae growing on large bodies of warm-water fish, purified wounds, collecting dead skin, bacteria and fungi.
Fish sailed "appointment", quietly open the jaws, gill slits relax and patiently, and sometimes even with obvious pleasure are waiting for the end of the process.
Cleaners acting usually in pairs, begin treatment with the eye, gradually moving to the gills, and then dived into his mouth and "patient."If the fish has a wound, it most often will sail, to cleaners treated her.In warm waters it is especially important, as the parasites develop it at high speed.That is, as you probably already understand, and "surgeon" and "dentist" - all this "profession" fish-cleaning.
the behavior of fish, using the services of cleaners
When the "patient" feels that he no longer needs help, he can file a shiner signal at the time of closing the mouth.But do not worry, he will not eat his "doctor", just so he says that in a hurry.
But sometimes fish cleaner can not resist the temptation otest piece nutritious slime covering the patient's body (it must be said that this is her favorite treat) and then outraged "client" shakes off the incompetent "physician" and departures.But, mind you, without trying to swallow it as a warning to the rest of the "health" of the brethren.
Why steam cleaners are better than one fish
Researchers from the University of Stockholm, find out what "profession" has a fish-cleaner, we discovered some interesting facts.It turns out that the fish often bite the mucus running alone.If the working couple and best of all - male and female, that such excesses are not observed.Why is that?
As it turned out, cleaners watching one another.And if a male (it is usually larger in size) discovers that the female has broken a rule, he pursues her to punish.Like this!But the females, because of this, work much better, and "clients" are more likely to just such mixed couples submarine "doctors."
And what "profession" has a fish-cleaner?
As scientists argue, removing parasites cleaner has a direct impact on the growth of populations of various inhabitants of the coral reefs.Where artificial reefs have been exempt from this type of fish, the number of other significantly decreased.So Cleaner - a sort of guardian of the abundance and diversity of fish species.
But the most surprising is the fact that monitoring of researchers, he is also a peacemaker.The reef, which is home cleaners, aggressive predators decreases.Even in aquariums, which contained the fish, predatory birds behave much calmer.
As you can see, the question of what "profession" has a fish-cleaner can give you some answers.
