Quick Answer
Rattlesnakes can be distinguished from non-venomous species by their distinctive rattle, triangular head shape, and vertical pupils. They also often have a broad, flat head and a heat-sensing pit between the eyes and the nostrils. A close examination of these features can help identify a rattlesnake.
Characteristics of Venomous Snakes
Rattlesnakes are part of the pit viper family (Crotalinae) and are known for their unique characteristics that set them apart from non-venomous snakes. One of the most distinctive features is the presence of a rattle, which is formed by loosely attached scales called “escutcheons” that vibrate when the snake shakes its tail. This rattle is made up of 5-10 scales, which can be counted to confirm the presence of a rattlesnake.
Distinguishing Features
A closer examination of the head shape and size can also help identify a rattlesnake. They typically have a broad, flat head that is distinct from the slender neck, whereas non-venomous snakes have a more tapered head that blends seamlessly into the neck. Additionally, rattlesnakes have a heat-sensing pit between the eyes and the nostrils, which is used to detect warm-blooded prey.
Safety Precautions
When handling snakes, it’s essential to exercise extreme caution and follow proper safety protocols. If you’re not confident in your ability to identify a rattlesnake, it’s best to leave it alone and seek assistance from a trained professional. Always wear protective gear, such as gloves and a snake hook, and never attempt to handle a snake that you’re not familiar with.
