Herpetological Highlights

Snakes can bite; and when venomous, these bites can cause serious harm. But how frequently do snakes actually deploy that venom? We look at a review breaking down current knowledge. We also check out a paper looking at local names for herpetofauna, and whether that is connected to the danger those species pose. Species of the Bi-week returns with another venomous beastie.
