Snakes, especially nonvenomous species, are not to be feared. In fact, they play an important role in our ecosystem. Here are a few facts about the suborder Serpentes:
- Snakes use debris to keep cool when it’s hot outside. Eliminating wood and brick piles, mowing grass and cleaning up trash can help keep them out of yards.
- Snakes are carnivorous. Small snakes will eat insects such as cockroaches and crickets, whereas large snakes will consume small animals such as mice, rats, lizards, birds and fish.
- Some species of nonvenomous snakes eat venomous snakes.
- Snakes eat their prey live or constrict it to death, and then swallow it whole.
- A snake’s hinged jaw enables it to eat prey that is larger than its body.
- Small snakes can slither through a hole as small as the diameter of a pencil.
- Although snakes don’t have ears, they “hear” sound waves that cause vibrations in their skulls.
- Regulations regarding snakes vary in each state. Some require a hunting license and others protect certain species.
- A snake’s skin is not slimy, but dry and scaly.
- Because snakes are cold-blooded, their body temperatures change based on their surroundings.
A snake will raise its body temperature by lying in the sun and lower it by staying in the shade.
- Snakes do not tolerate extreme temperatures, so they will seek shelter or debris when it’s hot or hibernate when it’s cold.
- As they grow, snakes can shed their skin several times over the course of a year. As they shed their skin, snakes become temporarily blinded because they must wait until their old skin splits at the head before they can crawl out of it.
