Helper cell

Heloderma horridum, also known as the Mexican beaded lizard, is a species of venomous lizard native to Mexico and Guatemala. It is one of only two species of venomous lizards found in North America, the other being its close relative, the Gila monster (Heloderma suspectum).

Description

The Mexican beaded lizard is a large, heavy-bodied lizard, reaching lengths of up to 91 cm. It is named for its distinctive skin, which is covered in small, bead-like scales. The coloration of the lizard is typically black or dark brown, with contrasting yellow or white spots or bands.

Distribution and habitat

The Mexican beaded lizard is found primarily in the Pacific Coast of Mexico, from Sonora to Guatemala. It inhabits a variety of habitats, including tropical deciduous forest, thorn scrub, and pine-oak forest.

Behavior and ecology

The Mexican beaded lizard is primarily nocturnal, spending the day in burrows or rock crevices. It is a slow-moving species, but can deliver a powerful bite if threatened. The venom of the Mexican beaded lizard is produced in glands in the lower jaw, and is delivered to the victim through grooves in the lower teeth.

Diet

The diet of the Mexican beaded lizard consists primarily of eggs, but it will also eat small birds, mammals, and other reptiles. It has a particular preference for the eggs of ground-nesting birds and turtles.

Conservation status

The Mexican beaded lizard is listed as Near Threatened on the IUCN Red List due to habitat loss and persecution by humans. It is protected by law in Mexico.
