Snakes are among the most feared animals. These reptiles can be as small
as the four inch long Barbados threadsnake or as large as the 40-foot long
anaconda. With over 3,000 species globally, snakes are found in almost
every biome. These legless, scaly vertebrates can slither, swim, and even
fly. Did you know that some snakes have more than one head or that some
female snakes can reproduce without males? Discover some unusual facts
about snakes that may surprise you.


Two-headed Snakes
Did you know that snakes can have two heads? This instance is rare and
two-headed snakes don't survive long in the wild. Each head has its own
brain and each brain can control the shared body. As a result, these animals
have unusual movements as both heads try to control the body and go in
their own direction. One snake head will sometimes attack the other as they
fight over food. Two-headed snakes result from the incomplete splitting of
a snake embryo. A complete split would have resulted in twin snakes, but
the process stops before completion. While these snakes don't fair well in
the wild, some have lived for years in captivity. According to National
Geographic, a two-headed corn snake named Thelma and Louise lived for
several years at the San Diego Zoo and produced 15 normal offspring.
