Micrurus mipartitus
Red-tail Coral Snake
Duméril, Bibron & Duméril, 1854
Detailed Texts Multi-lang
Elapid snake distinctive for its black body with thin white or yellowish rings and intense red coloration at the tip of the tail and sometimes on the head. Its pattern is less typical than other corals, with a prominent light nuchal band that gives it the name gargantilla (choker).

Sexual DimorphismPhysical differences in size, coloration, or morphology between males and females of this species.
Males Multi-lang
Males are usually thinner and with long tails.
Females Multi-lang
Females are more robust, necessary for egg production.
Evolutionary AdaptationsInherited traits and behaviors that improve the species' survival and reproduction in its specific environment. Multi-lang
Highly toxic venom: Despite being shy, its venom is very potent and designed for cold-blooded prey.
Main ThreatsDocumented pressures reducing the population: habitat loss, hunting, disease, climate change, and invasive species. Multi-lang
Habitat loss and human fear leading to its physical removal.
Interesting FactsSurprising or notable facts that highlight what makes this species unique or ecologically important. Multi-lang
It is considered one of the most common corals in anthropized areas, so human encounters are frequent.
