Habitat - Amphibians
begin their life in the water as gilled larvae (tadpole). Most amphibians
stay near to a water source where they are able to find the food they need
and other amphibians to mate with.
|
|
|
Movement – They begin their life in the water as larvae
or tadpoles with tales to guide them through the water. When old, most use
their legs to slither in an “s” shaped pattern.
|

|
|
Circulation/Internal Transport – The circulation system
in adults is linked to development of lungs and has a double loop carrying
poor oxygen to the heart and rich oxygen to the lungs.
|
|
|
|
Feeding/Digestion – Most amphibians use their mouths to
eat insects because they are carnivorous. They use extracellular digestion
through their cloaca and their complete gut.
|
|
|
|
|
|
Respiration –Adult amphibians breathe using their lungs,
mouth cavities, and skin however so salamanders have no lungs at all. The
skin is important because it removes the carbon dioxide and allows only
oxygen to pass through.
|
|
|
Nervous System – Their eyes are an important part
because they bulge out of the head and can move around in sockets. The
tymphanic membrane is like a ear and able to pick up vibrations and relay
them to the brain.
|
|
|
|
|
Reproduction – For the most part during reproduction the
female can lease as many as 200 eggs which the male then externally
fertilizes which develop by ovoviviparous. However some salamanders have
internal fertilization.
|
|
|
Excretion - The excretion process of the amphibian is through
extracellular digestion. The major body structure that aids in excretion
would be the anus. This is where most of the wastes of the amphibians get
digested from.
