Nima yeydi?

Its diet is mostly mammals, especially the Santa Catalina deer mouse, with some lizards. It holds its prey in its jaws until the venom takes effect, rather than biting and releasing it.1

Faktlar

It is one of the few rattlesnakes that has lost its rattle. The tail tip falls off with each shed instead of forming a new segment.1

Although it is a rattlesnake, it is a swift and skilful climber, and individuals were most often found in low bush branches during the hottest month, July.1

Its main prey, the Santa Catalina deer mouse, lives only on this island, so the snake's food supply is also very limited.1

It does not hibernate, and the evidence suggests it is nocturnal even in winter.1

Its closest relative on the mainland is the red diamond rattlesnake, which eats a much wider range of prey, including frogs, birds and other snakes.1
