What is the common name of Crotalus horridus?

Crotalus horridus is commonly known as the Timber Rattlesnake. This species is a type of venomous snake found primarily in the eastern parts of the United States. The Timber Rattlesnake is identifiable by its distinct rattle, which it uses as a warning signal when threatened, and can vary in color, often exhibiting a pattern of dark bands on a lighter background.

This species plays an important role in its ecosystem as both a predator and prey. It primarily feeds on small mammals, birds, and sometimes frogs or lizards, and is known to inhabit forested areas, mixed woodlands, and sometimes mountainous regions.

The other options refer to different species or animals that do not match the scientific name provided. The Eastern Coral Snake is a different species known for its red, yellow, and black banding, while the Cotton Mouth Snake (or Water Moccasin) is a semi-aquatic snake with a different habitat and appearance. The Brown Recluse Spider is an arachnid entirely unrelated to the rattlesnake in terms of classification. Therefore, the Timber Rattlesnake is the accurate common name associated with Crotalus horridus.
