Usually 3–8 ft. (max. ~13 ft.)


Large, heavy body is grayish, tan, or light brown. Back is marked with darker brown saddle-like bands; bands on the tail are reddish-brown. Scales are smooth. This snake gives birth to live young (does not lay eggs).


Introduced in southern Florida, it has become established in at least one location in Miami-Dade County. It is usually found in forested areas, including pine rocklands and tropical hardwood hammocks. This species is not native to Florida – it was introduced as a result of the unethical and illegal release of pet snakes.
