Junior School: Adaptations

“Books are a uniquely portable magic.”


An adaptation is a mutation, or genetic change, that helps an organism, such as a plant or animal, survive in its environment. Due to the helpful nature of the mutation, it is passed down from one generation to the next.



Animals migrate for a variety of reasons. Migration is a behavioral adaptation that helps animals survive.




Seven  animal adaptations are

  • camouflage
  • mimicry
  • having a limited diet
  • poison
  • reduction of size and stature
  • changing of habitats




Biomes are a way to divide the Earth's surface. These divisions are based on climate patterns, soil types, and the animals and plants that inhabit an area. There are biomes on dry land and in water. Every inch of the Earth's surface is a part of one or more biomes. 

There are a couple of different ways to look at the number of biomes. Some like to divide biomes into five basic types: aquatic, forest, desert, tundra, and grassland. These five types of biomes can be further divided by differences in seasons or animal and plant species. 

Animals (four to five) representing Australia’s biomes:

  • Rainforest: Magnificent tree frog*, Jungle carpet python*
  • Desert: Bredli python*, Woma python*, Shingle back lizard*, Black headed python*
  • Freshwater: Saw-shelled turtle*, Brisbane River turtle*
  • Bush: Koala*, Squirrel glider*
  • Alpine: Blue tongue lizard* *


Animal Adaptations that are suited to a particular habitat and conditions.

A healthy ecosystem includes a diverse range of organisms each suited to particular conditions. Over time organisms have developed adaptations as a response to their environment. These adaptations enable the organism to better fit with its 'environment' resulting in an improved chance of survival. Provide examples of adaptations that are external structures, internal structures or exhibited behaviours.
