594:, are well known as one of the most snappy and combative rat snakes. In general, their defense system can be broken down to two levels. The first line of defense involves specific behaviors that they use to warn the intruders. One of the most common ways is by coiling their bodies and vibrating their tails, which simulates a rattle. Fox snakes,
633:
spp. move forward using side-to-side, serpentine movement. They use the curved ventral scales of their bodies to grab the rough ground surfaces and then push against the ground to generate a forward movement. Thus, the smoother the ground is, the harder it is for them to move across it. Many species
544:
spp. seek an appropriate place to lay the developing eggs. They usually lay eggs in the soft heart of a rotten log or in sandy soil under a rock. A good place for laying eggs is one that is damp but not wet, and warm but not hot. After laying eggs, the female snake covers them up with sand or soil,
371:
spp. have very developed sensory organs which support their daily activities. They have internal ears that enables them to detect sounds at low frequencies. The ears consist of a single ear bone connected to a jaw bone. Compared to other snakes, they are considered to have highly developed vision
686:
spp. live in a great variety of environments, depending on species and subspecies. Most are terrestrial or semiarboreal, but some burrow in sand or loose soil. The genus formerly contained species found on every continent except
Antarctica. Taxonomic revisions have renamed most of these former
674:
spp. kill the prey by creating enormous pressure on the prey's chest. As they continue to coil more tightly, the pressure on the chest prevents the blood from circulating into the heart, which eventually leads to heart failure. They usually bite the prey first to maintain their grip on the prey
474:
spp. hibernate in the rock crevices, rock faults, and burrows. However, other species choose to hibernate in rotting logs, roots of trees, and hollow spaces in elevated tree trunks. Some snakes that live close to human communities even hibernate in old wells and barns.

Jacobson's organ, they use their tongues to transport air and ground molecules to Jacobson's organ. Then, the organ analyzes the molecules to identify the scent. Among these detectable scents are
