Paano ito makikilala

  • Black with yellowish spots or bands.1
  • Small, beadlike scales that do not overlap, which give it its name.1
  • Stocky body with a broad head.1
  • Short tail that stores fat, and does not regrow if broken.1
  • Adults are 57 to 91 cm long.1

Madalas mapagkamalang: The Gila monster is its closest relative and looks similar. The Mexican beaded lizard is larger, and its colours are duller, black with yellowish bands.1

Lakas ng kamandag

Mga kagat

Lumalabas ang kamandag sa pangil o ngipin nito kapag nangangagat ito.

Ano ang epekto ng kamandag nito?

Its venom is a weak hemotoxin, meaning it attacks blood and tissue. It can cause respiratory failure, which is when breathing fails. In humans, bites cause severe pain that can spread well beyond the bite and last up to 24 hours, along with swelling, weakness, sweating and a rapid drop in blood pressure.1

Human deaths from its bites are rare. Eight human bites were documented in the past century, and almost all happened when people prodded captive lizards with a finger or bare foot.1
