The Mexican beaded lizard (Heloderma horridum) is the most famous of the four species of venomous beaded lizards found principally in Mexico and southern Guatemala.

Diet
Mexican beaded lizard's dietary habits primarily encompass small mammals, illustrating its carnivorous nature. While it significantly favors rodents and rabbits, it also ingests small birds and eggs when available, demonstrating dietary diversity.
Appearance
Mexican beaded lizard is a moderately sized reptile with a robust, cylindrical body, covered in rough, bumpy scales. Its skin exhibits a striking black and yellowish-brown pattern. Its tail is thick, often used for storing fat, and has a similar colouration pattern. Mexican beaded lizard is distinctive for its bead-like skin texture and venomous bite, but lacks prominent differentiation based on age, gender, or subspecies.
Behavior
Mexican beaded lizard is a solitary, predominantly diurnal creature. Notably, it is one of the few venomous lizards, using venom for predation rather than defense. It has a slow, deliberate movement, consuming a wide range of prey including insects, small birds, and mammals. Mexican beaded lizard uses burrows for rest and thermoregulation, often occupying abandoned rodent burrows. Territorial disputes, rare due to its solitary nature, involve physical threats and posturing but rarely actual combat.
