Personal Information
The Zoo’s beaded lizard, Guapo, was born in 1972 and weighs 14 pounds. While a sluggish animal most of the time, the beaded lizard can become aggressive when taken out into the sun. His name means handsome in Spanish.

Status in the Wild
International Union for Conservation of Nature (IUCN) Red List status: Least concern. Mexican authorities state the bearded lizard’s status as threatened. Deforestation and human persecutions are two reasons for the population decline. However, the beaded lizard is protected under Mexican law and in Guatemala.

Habitat
The beaded lizard lives in tropical deciduous forests and tropical scrubland.

Diet
The beaded lizard eats other lizards, bird eggs, and occasionally rodents and small mammals.

  • Heloderma means studded skin, and horridum means horrible. Thus, the beaded lizard is also named the horrible studded lizard.
  • Beaded lizards are one of two species of venomous lizards in the world.
  • Along with a venomous bite, the jaw muscles of a beaded lizard are strong enough to crush prey.
  • Beaded lizards are nocturnal animals that spend 98% of their lives underground.
  • The beaded lizard is named for its armor-like protrusions called ostioderms, which look like beads.
  • Beaded lizards are surprisingly good burrowers, swimmers and climbers.
