They even have a sophisticated piece of anatomy used to process scent, called a Jacobson’s … In general, there is not a speed that is "too fast", but be sure to take in the picture of the whole animal. When a snake flicks its tongue in the air, it picks up tiny chemical particles. The gopher snake is a nonvenomous constrictor. This article was originally published on The Conversation by Andrew Durso. Italian astronomer Giovanni Hodierna thought snake tongues were for cleaning dirt out of their noses. In the 17th century, a widely held belief was that, like other reptiles such as chameleons, snakes caught insects with … Snake ecologist Chuck Smith at Wofford College found evidence that male Copperheads have longer, more deeply forked tongues than females, which presumably enhances their ability to find mates.
