Amphibians

Amphibians are vertebrates that live both on the land and in the water.  They are ectothermic (also called cold-blooded) meaning that they cannot regulate their own body temperature.  An Amphibian's body temperature fluctuates according to its surroundings.  They also have moist skin, webbed feet, and lay eggs.  At various stages of development, they breathe through gills and then lungs.  Examples:  salamanders, frogs, and newts.

Invertebrates

Invertebrates are those animals that do not have a spinal column. They are smaller than vertebrates, but they are great in numbers! It is estimated that 97 percent of all animals alive today are invertebrates.

Mammals

Mammals are animals which form the Mammalia class. Their defining features include animals that: 

- breathe air;
- are warm-blooded - the same temperature no matter what their environment;
- have a backbone;
- grow fur or body hair at some point in their lives;
- females produce milk for them in mammary glands;
- Note:  MOST mammals have teeth with the exception of the ant eater.
- Note:  MOST mammals bear live young.

Mammals live in all sorts of environments - on land, underground or in the ocean.  Cats, cows, elephants, and even whales are all mammals!  Some mammals such as bats can fly!

Mammals are further divided into three different types depending on how they give birth and look after their young:

- Live birth mammals  - Those to whom babies are born alive:
- Marsupials - Mammals that carry their young in a pouch.  Think of the kangaroo, koala and opossum.|
- Egg laying - There are special mammals called monotremes that lay eggs.  These are the Duckbilled Platypus and the Long-nosed Spiny Anteater.
