THE SNAKES
THE OPHIDIA OR SNAKES.
Snakes are closely related to lizards. Some lizards, as you have already seen, are very much like snakes in form. The main distinguishing features of the snake are the elastic tissue which connects the two halves of the lower jaw and the absence of eyelids. Snakes are carnivorous and are capable of moving with great ease and swiftness notwithstanding their lack of limbs. They cast their skins several times a year. Many of the snakes are poisonous, and authorities tell us that there is no external characteristic that indicates which are poisonous and which are not.
