Gila monster (Heloderma suspectum). This venomous, nocturnal lizard inhabits desert areas of North America, from Nevada and southeastern Utah in the USA to Sonora in Mexico. It grows to a length of 60 centimetres, and preys on nestling rodents and birds, and on the eggs of birds and reptiles. The Gila monster stores fat in its tail for use during times when prey is not available. Among the recorded instances where humans have been bitten by Gila monsters, about one third have proved fatal. To date no effective antidote has been developed. Photographed in the Sonoran Desert, Arizona, USA.
