Mojave Desert Sidewinder
Crotalus cerastes
36.4618, -116.867
Field Notes
Description:
It is sometimes referred to as the horned rattlesnake because of the raised supraocular scales above its eyes. This adaptation may help shade the eyes or prevent sand drifting over them as the snake lies almost buried in it
These snakes are venomous, but possess a weaker venom than many other rattlesnakes. This, together with the smaller size of their venom glands, makes them less dangerous than their larger relatives.
Habitat:
Seen at night in sand dunes. The species is nocturnal during hot months and diurnal during the cooler months of its activity period.
Sidewinder rattlesnakes can use sidewinding to ascend sandy slopes by increasing the portion of the body in contact with the sand to match the reduced yielding force of the inclined sand, allowing them to ascend up to the maximum possible sand slope without slip.
Notes:
C. c. cerastes -- Mojave Desert subspecies
