WE are all used to seeing certain animals in particular places.
But some are found in unexpected environments.
Some examples include:
lThe flying squirrel, which has a flap of skin along its flanks that acts as a parachute. He uses it to glide from tree to tree.
lThe Emu, which is a bird that has big, powerful legs but no wings.
lThe sea snake that spends its whole life in the water and is sometimes many hundreds of kilometres from land.
