The Mexican Bee Lizard (Heloderma horridum) is a species of venom lizards mainly found in Mexico and southern Guatemala. Until recently it was thought to be the only venomous lizard in the world.
The venom of this lizard contains several substances, it is useful in fighting diabetes and drug production.
It is a species threatened by the gradual loss of habitat.
Bearded Lizard has only one species in the near life (Heloderma suspectum) capable of producing venom. It also has similarities to monitor lizards.
The species was first described in 1829 by Arend Wiegmann. He initially called it Trachyderma horridum, and six months later he renamed her as we know it today: Heloderma horridum.
The Mexican bearded lizard has 4 subspecies:
- Mexican beaded lizard (Heloderma horridum horridum)
- Black beaded lizard (H. h. Alvarezi)
- Rio Fuerte beaded lizard (H. h. Xasperatum)
- Motagua Valley beaded lizard (Heloderma horridum charlesbogerti)
Food Mexican Beaded Lizard
The lizard's main food consists of bird eggs and reptiles.
It is a semi-arboreal species, was seen catching in the trees after prey.
Occasionally eat small birds, mammals, frogs, lizards and insects.
It was found that in captivity refuse other types of food than eggs.
Features Mexican Beaded Lizard
The adult specimens are 60-90cm in length, much larger than the Gila monster. Males are bigger than females. Although both sexes have large heads, males tend to have something bigger than females.
The short tail has the role of fat storage for the animal to survive poor months in food. Unlike many other lizards, if the animal stays without a tail it will not grow.
The venomous glands of the Mexican lizard with beads are actually altered salivary glands.
When this bite takes its prey and basically chews the place for the saliva to come in contact with the victim's blood and act as soon as possible. The wolf's lizard is quite weak and the human deaths caused by this lizard are rare.
The reason why the bite of the lizard is dying is the inability to breathe, sweating, moles, etc. The venom is not severely tormenting the man for 24 hours. Enough to find an antidote. The lizard is immune to her own venom.
