Many are vividly banded with red, black, and yellow or white, although some species lack red bands or are mostly black. The colorful banding pattern is warning coloration for potential predators, but can also act to conceal.

The neurotoxic effects of its potent venom cause rapid paralysis and respiratory failure among its favorite cold-blooded prey, snakes and lizards. It prefers tiny blind snakes throughout its range, but will eat shovel-nosed snakes, black-headed snakes and whiptail lizards.
