2. THE SNAKE
They are reptiles, legless (without legs) and
carnivorous (meat eaters).
They don’t have eyelids and external ears (like
Covered by scales.
Found on every continent (except Antartica)
Some species like cobras and coral snakes, use
venom to paralyze or kill their prey before
eating it. The venom is modified saliva
Others kill by constriction
They eat small animals including lizards, other
snakes, small mammals, birds, eggs, fish,
snails or insects
10. Winter dormancy
In regions where winters are colder than
snakes can tolerate, local species will
brumate. Unlike hibernation, in which
mammals are actually asleep, brumating
reptiles are awake but inactive.
Individual snakes may brumate under rock
piles, or inside fallen trees, or snakes may
aggregate in large numbers.
All snakes are carnivorous but they cannot bite or
tear their food to pieces, they must swallow prey
whole. The body size of a snake has a major
influence on its eating habits. Smaller snakes eat
smaller prey. Juvenile pythons might start out
feeding on lizards or mice and graduate to small deer
or antelope as an adult, for example.
Snakes do not normally prey on humans.
Most snakes prefer to avoid contact and will
not attack humans. With the exception of
large constrictors, nonvenomous snakes are
not a threat to humans. The bite of a
nonvenomous snake is usually harmless; their
teeth are not designed for tearing but rather
grabbing and holding. The possibility of
infection is present in the bite of a
