More Information

Rio Fuerte beaded lizards can reach up to 30 inches from head to tail. They have a broad, flat head and venom glands in their lower jaw. Their bodies are long and heavy and covered with bead-like scales that form yellow and black stripes. These long-clawed lizards are carnivorous, eating insects, small rodents, lizards, snakes, birds, and eggs. They become sexually mature after three or four year.

Did You Know?

Rio Fuerte beaded lizards paralyze their prey with venom mixed into their saliva.

These lizards are frequently found in abandoned mammal burrows and near sources of permanent water.

They store fat in their tail, using it as a reserve energy source when food is scarce.
