Appearance
Black-tailed rattlesnake is a medium-sized snake with scales covering its robust, cylindrical body. It exhibits a base coloration of brown, overlayed with lighter crossbands that contributes to effective camouflage. Unlike some snakes, it lacks wings or fins, but features a distinct rattle at the end of its tail, a signature characteristic of its species. Both sexes and all ages have similar appearances, with no significant differences noted.

Exceptionally solitary, black-tailed rattlesnake engages in aggressive territorial defense primarily during mating season, rattling its tail as a warning. Unlike many species, black-tailed rattlesnake does not exhibit migratory behavior, demonstrating high site fidelity.
