Northern Pacific Rattlesnake

Crotalus oreganus oreganus


She was captive-bred at a private facility in Texas. She was transferred to CuriOdyssey in July of 2008.

Fun Facts

Young rattlers leave their mothers at just a few weeks old, but when it’s time to hibernate in the winter, they follow their mother’s scent trail and use the same den. Future generations will also use the same den—some have been used for over 100 years!

Who would guess that rattlesnakes are good swimmers? They’ve been found several miles out at sea!
