Aruba Island rattlesnake
At the Detroit Zoo
The Aruba Island rattlesnake can be found inside the Holden Reptile Conservation Center, located near the middle of the park. There, visitors can learn about the 70 different species (and approximately 180 individuals) of reptiles at the Detroit Zoo, one-fifth of which are considered threatened or endangered in the wild.
One of the rarest rattlesnakes in the world, its small body and brown color make it very hard to see in the wild. Its V-shaped head indicates that it belongs to the viper family.
