The research, which was supported by the Natural Sciences and Engineering Research Council of Canada, was detailed in the Journal of Experimental Biology. The snake, apparently feeling threatened by van Doorn’s about face, restricted blood flow through its spectacle scales. "This work shows that the blood flow pattern in the snake spectacle is not static but rather dynamic," van Doorn said in a statement.įuture research is needed to investigate whether this trait can be found in other species.

The opposite was true as the snakes were shedding their skin the spectacle vessels remained dilated, keeping the blood flow continuous, which probably supports cell growth as the snake renews the outer layer of its skin, according to the study.
They constricted these vessels, reducing blood flow for up to several minutes and ensuring topnotch visual clarity in case they needed to defend themselves or flee from a predator, the researchers said. He found that the blood vessels constricted and expanded in a consistent cycle while the snakes were resting so that blood cells wouldn't pool up in front of the animals' eyes and obscure their already limited vision.īut faced with a threat (in this case, a human approaching their terrarium), the snakes abandoned this rhythm. Van Doran further investigated this feature. The eyeglass chain is very delicate and gorgeous.It is a great jewelry, both sides of the high elastic silicone rubber tip firmly entangle the temples.

While examining the eye of a coachwhip snake, study researcher Kevin van Doorn, of the University of Waterloo in Canada, said he noticed a network of blood vessels in this see-through layer of skin. Brille means spectacles or glasses in German, Norwegian, and Danish, as well as shine in French and Spanish.
