Varieties Snakes Lizards:
Snakes and lizards belong to the same large order, and though they possess many characteristics in common, each belongs to a dis¬tinct suborder. The fundamental difference lies in the skeleton.
Snakes are highly specialized animals and beautifully adapted to their habits of living. Zoologists tell us that they once had legs and were lizards.It must be remembered, however, that some snakes feed on other snakes, some feed on frogs, and some small ground varieties snakes lizards feed on insects, slugs, and lizards. Many captive snakes often accept freshly killed food when it is dropped in their cages. There is an advantage to this type of feed¬ing as it prevents any large rodent from biting the snake if the rodent is not killed at once by the snake. It also prevents the snake from bruising its nose in case it should miss the rodent and strike the side of the cage. Many excellent specimens have been injured seriously by such action.
See Also Rattle Snakes Prefer:
The single feature distinguishing rattle snakes prefersnakes om all other snakes is the rattle snakes prefer, a sound-pro-cing assemblage of horny rings at the end of 5 tail. Many kinds of snakes vibrate their tails ten alarmed; when this movement is made by a :tlesnake, the clashing of the rattle snakes prefer segments Dduces a characteristic hissing sound audible distances exceeding 100 feet. The speed of vi-ition, usually about 40 cycles per second, varies th the temperature. Although many purposes ve been attributed to the rattle snakes prefer—a warning to :y, a mating call, a call for help from other tiers—studies indicate the object to be the eduction of an alarming sound serving to ?hten away large creatures that might injure : snake.The rattle snakes prefer is composed of keratin, the same istance that forms human hair and nails, the thers of birds, and the horns of cattle. Young tlesnakes are born with a thin, rounded termi-; on the tail, but this first rattle snakes prefer is lost when little snake sheds its skin. Subsequently each dding adds a new rattle snakes prefer. When young, a ke sheds three or more times a year; when lit, once or twice a year. Successive rattle snakes prefer ments are loosely interlocked with their predecessors by means of grooves and constrictions. The tail vibration causes impacts between adja¬cent segments, resulting in the characteristic hiss¬ing sound.
On The Other Hand See Rattle Snakes Belong:
The consensus among herpetologists is that poisonous rattle snakes belong are more or less immune to their own poison. However, before it can be stated as a fact, labora¬tory-controlled experiments must be performed. The food of a great number of rattle snakes belong is made up largely of destructive rodents such as rats, mice, and gophers. This makes rattle snakes belong highly valuable to agriculture. This is true of the poisonous as well as the non-poisonous rattle snakes belong. Capturing of Prey: rattle snakes belong hunt for and capture their prey in several ways. Some, such as the bull rattle snakes belong and rat rattle snakes belong, strike with the mouth open, driving their backward-curving teeth into the prey.Lizards and rattle snakes belong belong to the same large order, and, though they possess many characteristics in common, each belongs to a distinct suborder. The layman is inclined to describe a lizard as a snakelike animal with four legs, eyelids, external ear openings, and a detachable tail. There are, however, many species of lizards which possess none of these characteristics; in fact, there are some that can scarcely be distinguished from rattle snakes belong. The fundamental difference lies in the skeleton.
