Who golubiy balistol
Hollywood movies taught us to fear sharks and giant octopuses, but actually clash with these monsters for any diver is less likely than, for example, receiving an Oscar for a film about these creatures. Much more likely to suffer from such fish as golubiy balistol ( Balistoides viridescens ), he’s a titan triggerfish .
In the family synorogenic ( Ballistidae . eng. – triggerfish ), about 40 species of fish, but our hero stands out by the combination of considerable size (up to 75 cm, 10 kg) and aggressive behavior towards divers. underwater hunters and snorkelers.
Triggerfish lives in lagoons or on outer slopes of reefs. Usually, the fish lives alone or in pairs. It feeds on some kinds of corals, starfish, sea urchins, snails, bivalves, and algae.
To catch prey balistol can release a jet of water from its mouth to rake the sand or turn over large blocks of stone, if he knows that there sits the potential victim.
The causes of aggressive behavior
It should be understood that you have the guts, he will not. Even hunting for small fish is not part of his plans, not to mention the huge carcass, often dressed in a tasteless suit .
Sometimes there are individuals with a bad temper, pursuing divers without any videosbikini. For example, the legendary Trevor the Triggerfish (Balistol Trevor), the attacker often on divers in the area of White Rock on Koh Tao and chased them for a few minutes.
But most often the reason for the attack is that you are swimming close to its nest or place prepared for him. Nest poluboyarova of balistica is up to 2 meters in diameter and 0.75 metres deep, but in practice it is invisible to man. It is the instinct to protect offspring and pushes him to attack a much larger individual.
Before the attack on the diver raises triggerfish spin fin and turned to the side to inspect you. This is enough to understand his intentions.
What to do after becoming a victim of attack
Balistol perceives the territory, located above the nest, as his property, requiring protection from uninvited guests. He guards the space having the shape of an inverted cone. This is most likely caused by differences in vision of this fish. Therefore, the most logical behavior is to turn around and retreat, moving in a horizontal plane. Your ascent to the top will soothe balistica and can even be interpreted by them as an approximation to the nest. Most likely the fish will attack you until you move enough in her view to the distance, and therefore undesirable to lose her.
Divers can scare off the trigger, releasing the air from the reserve tank in his direction, he usually does not like. I successfully fought back with the help of long Freiverkehr last, directing them in the direction of the angry fish and knocking her on the head. The fins did not suffer, although there are cases when they chew through it. Bright diver’s flippers. photo and video cameras, the details of the suit can divert the attention of the fish.
Damage is the lesser evil, because there are known cases pokusannyh arms and legs, torn earlobe, torn lip and perforated at the buttocks of the hapless victims.
Knife. likely to help only the big luck the side the fish is covered in extremely tough scales, causing injury only in the eye or open mouth. I myself am at the point of attack was covered with a hand, still not realizing the seriousness of this seemingly silly little fat man, for which he was awarded a pair of shallow incised wound on the lower side of the palm.
Toxins in fish
Eating this type of fish can cause serious health problems. Triggerfish accumulates ciguatoxin – the poison secreted by the dinoflagellates Gambierdiscus toxicus type . and passed up the food chain. Therefore, the older and larger the fish, the more toxin it contains. Fish and shellfish are not sensitive to it, unlike humans.
This poison can lead to ciguatera – disease, which manifests itself in the form of various disorders in the gastrointestinal tract and nervous system. In severe cases, paralysis or cardiac arrest, leading to death. The symptoms manifest themselves after 1-6 hours and can last from several days to several years with breaks.
Ciguatoxin resistant to freezing and high temperatures, so cooking the fish food in no way diminishes its action. There are no effective means of treatment or neutralization, therefore at a poisoning victim needs to rest and symptomatic treatment.
It is believed that the attack poluboyarova of balistica some amount of toxin can enter the bloodstream when they bite. Reliable information about it I can not find, but in the palm of the victim feels slight numbness of the muscles, not corresponding to their shallow depth.
The main areas of habitat poluboyarova of balistica Red sea and Indo-Pacific region from the coast of South Africa to Japan. Very often the victims of attacks of this fish are divers in Thailand. where it is particularly aggressive.
