Undoubtedly, one of the most genius heads of the animal kingdom (next to the octopus) is that of the hammerhead shark. These aquatic predators have the particularity of having their head in the shape of a T, with an eye on each side of it, a form that gives them the popular name of the species. But why this head?
For centuries, zoologists speculate with the function that this head has in these animals, and what evolutionary advantage it represents in relation to that of normal sharks. Today the professor of the University of Hawaii Timothy Tricas publishes his conclusions in the Journal of Experimental Biology, which clear several of the doubts in relation to it.
In a precise experiment, Tricas and his team placed several species of sharks (including hammerhead sharks) in aquariums, to which sensors were placed on the skin to measure their brain activity. Subsequently, light was emitted from various angles and the reception capacity of the different sharks was measured.
Before light emitted from different places, the hammerhead sharks were able more than any other species to measure the distance and intensity of the illumination, something in which the position of their eyes influenced.
According to Tricas, the great advantage of the head of hammerhead sharks is their binocular vision capacity. This type of vision makes it possible to couple the vision of one eye with another, in order to precisely measure the distance and position in the space of objects. In addition, in the case of the hammerhead shark it gives it 360º vision capability, a perfect use for hunting its prey.
