The rattlesnake is a member of the pit
viper family. It is the only venomous snake native to California. Six species
are found in various areas of the state encompassing nearly the whole state,
from below sea level to about 11000 feet. Rattlesnakes are an important part of
the ecosystem, preying on rodents, birds, and other small animals, in turn they
are preyed on by certain birds.
Rattlesnakes! The word alone fills most people with
fear and anxiety, because they have no experience in dealing with snakes. Yet
we should learn to appreciate the rattlesnake as one of the most efficient and
specialized predators on Earth. Many rattlesnakes struggle to survive as humans
move in on their habitat. And some people feel that the only good rattlesnake
is a dead one! Read on to discover cool stuff about rattlesnakes and why we
need them.
Rattlesnakes are known for their relatively heavy
bodies and diamond-shaped heads. They are considered to be the newest or most
recently evolved snakes in the world. Rattlesnakes have either a rattle or a
partial rattle made of interlocking rings, or segments of keratin, the same
material our fingernails are made of. When vibrated, the rattle creates a
hissing sound that warns off potential predators. It is an extremely effective
and highly evolved predator-avoidance system.
Rocky crevices, burrows, and leaf litter all make safe
dens for rattlesnakes. Those in more temperate zones, where temperatures can
stoop to 40 degrees Fahrenheit (4 degrees Celsius), may hibernate in the
winter. They emerge from their den in the spring to warm up. As cold blooded
creatures, rattlers depend on the sun to warm them up to optimal temperatures
and shady places to cool off. Often, a flat surface like a paved road attracts
a snake seeking to sun itself.
