The wilder Vegas: Wild animals that can be spotted near the city

Spiders

Black Widow spiders and Desert Tarantulas are common in the desert surrounding Las Vegas. Though neither are actively aggressive towards humans. The Black Widow is one of the most common spider species in Nevada, and is extremely dangerous because of its strong defensive behaviors. It will immediately attack and bite when threatened or disturbed. The venom of the Black Widow is considered to be 15 times stronger than that of a rattlesnake.
