Pantherophis alleghaniensis
pantherophis alleghaniensisAlso known as Black Ratsnake, Gray Ratsnake, Chicken Snake, Midland Ratsnake
Central ratsnakes are powerful constrictors renowned for their exceptional climbing ability, often scaling vertical trees and barn walls in search of prey. Juveniles sport a distinct blotched pattern that typically darkens into a glossy black or grey coat as they mature into adults. When threatened, they frequently freeze in a kinked posture or vibrate their tails against dry leaves to imitate a rattlesnake.
