Snake Habitat

• Snakes can live in Asian, South America, North
  America, Europe, Africa and Australia. The
  snakes live in forests mostly and live under
  rocks, the rivers, water, grasslands, caves and
  holes. Some desert snakes live under the sand.
  They are also found in prairies.

How do they eat?

• Catching and eating food is a very specialised
  activity. Snakes dont have claws with which to
  grab, tear or hold their food, and they are
  unable to chew because their teeth and hinged
  jaws aren't designed for the purpose to chew
  their food. Snakes are able to dislocate its
  upper and lower jaw and separate the two sections
  of its lower jaw. This allows it to move each jaw
  by itself, and spread open its head and throat
  to swallow the prey much larger than the usual
  diameter of its mouth. Digestion takes place in
  the stomach, with the aid of very strong
  digestive juices. Unlike endothermic animals, a
  snake's food digestion rate is influenced by
  external temperatures .

What do they eat?

• It depends on what kind of snake it is, and
  Snakes eat insects like termites, mice, rats,
  frogs, fish, and even other snakes and reptiles
  Some snakes eat eggs, swallowing the egg whole,
  crushing it with its powerful muscles, and later
  regurgitating the eggshell. Larger snakes, such
  as the anaconda which drops on its prey from the
  branches of a tree, will eat monkeys, pigs,
  goats, and even deer. Snakes eat their prey whole
  and are able to consume prey three times larger
  than the diameter of their head because their
  lower jaw can separate from the upper jaw. To
  keep prey from escaping, snakes have rear-facing
  teeth that hold their prey in their mouths.
  Venomous snakes inject their prey with venom,
  while constrictors squeeze their prey. They do
  not need to hunt everyday. Anacondas and pythons
  can survive for up to a year without food after
  feeding. Snakes hunt mostly at night.

What is their niche?

• Many snake species eat rats and mice, which are
  pests to humans. This includes venomous species
  which eat large numbers of rodents. Other snake
  species eat insect pests. So this means that
  snakes are predators to rodents and most snakes
  are carnivores. A snakes success is their
  ability to change their diet in different
  seasons, eating whatever they can find.

  predators. One of their predators are the same
