Micrurus corallinus

Micrurus corallinus, also known commonly as the painted coral snake, is a species of highly venomous snake in the family Elapidae. The species is native to eastern South America (Argentina, Brazil, and Paraguay). There are no recognized subspecies. Local common names for Micrurus corallinus include cobra coral pintada, mboi-chumbe, vibora de coral, boicora, bocora, coral-verdadeira, ibiboboca, and mboi-yvyvovo. The painted coral snake is a medium-sized tri-colored snake which can grow to a total length (tail included) of 98 cm (39 in), but most are closer to 65–85 cm (26–33 in). It is a snake with nocturnal habits found on the coastlines, in leaf litter, and under logs and stones. Its diet is based on caecilians, amphisbaenids, lizards (including gymnophthalmids), other snakes (including colubrids). The head color is black with a white or yellow band on the posterior portion of the parietals. This band narrows strongly mid-dorsally. The body has wide red rings that are separated by a series of 15–27 (usually 17–21) narrower black rings with white borders.
