The Aruba Island rattlesnake (Crotalus unicolor), these snakes are found only on the island of Aruba, where they are mostly limited to the rocky, dry southern tip of the island. Due to their extremely limited geographic range, about 230 animals are left in the wild, and the ever encroaching human habitation into their territory (with only about 25 square kilometers left undeveloped), the Aruba Island rattlesnake is among the rarest rattlesnakes in the world. While exporting from the island is illegal, it has no other legal protection on the island either. The snake is now a part of the Species Survival Plan for captive breeding.
