Like other rattlers, females give birth to 6-21 fully loaded live young.

These snakes can often be found in gopher tortoise burrows, leading to humans gassing the burrows, which kills other species as well.

Venom is hemotoxic, targeting red blood cells & disrupting blood clotting

They’re ambush predators.
