Dear English-speaking readers, this page is an automatic Google translation from a post originally written in French. My apologies for the weird sentences and the funny mistakes that could have been generated during the process. If you can read French, the original and correct version can be found here:
Everyone is scared of sharks. It's silly. It is rare that the shark eats of the man (whereas the opposite is not it). In fact, there is more danger for divers: the triggerfish mustache or ballista olive, also called ballista titan.
The triggerfish is a pretty big fish, very fast. It is named after trigger-fish, in English, because of its caudal fin that shines like a trigger (Trigger) when he takes action.
It is one of the few fish that divers can fear attacks ... with, of course, the fierce clownfish ! ! !
Admire the teeth of the beast ... And the little cleaner shrimp, perched without fear on the tip of his nose!
This photo is dated my journey of 2006 Perhentian Islands, Malaysia. A very wise ballista like that, the time of the passage to his "cleaning station", it is not so frequent ...
Video: the baliste meal
Below, shot in Bali in July 2008, a short video of the beast, demolishing the reef with big teeth:
Avoid approaching the "nest"
In fact, it is the male who is aggressive, during the mating season, when he keeps the nest. If you approach it too closely, it drives you out of its territory and does not hesitate to bite with its naughty big teeth of rabbit to better convince you to leave. And he swims fast.
Better to circumvent the place, because the ballista defines its territory from the bottom to the surface.
The triggerfish also has an inverted cone vision. The frequent mistake of the divers is to take a distance from the top, while it suffices to move away while remaining at the same depth, preferably facing the animal: one swims calmly backwards, presenting the palms. Thus, if he takes the urge to bite something, it will be the plastic fins, rather than fat calf or a finger.
The other species of ballista, like the nice ballista-clown, with its white dotted livery, are not aggressive like the ballista titan.
In Koh Tao, Thailand, titan triggerfish have become particularly aggressive because of the high concentration of divers.
A few years ago, a ballista was nicknamed Tyson by the dive-masters of the area. The beast had, it seems, tasted the ear of a customer ... (like the boxer Mike Tyson during a fight).
