Many of the summer sports are familiar, but some you may not know about. Triatholon is new to the Olympics. Olly is a Kookaburra. Kookaburras spend most of the day on high branches. Platypus and Echidnas are a special kind of mammal because their babies are born differently.
Platypus eat insect larvae, shrimps and worms.
They find their food in the water. Echidnas come out at dawn and dusk to feed. You might see other animals if you were visiting Australia. Be patient - it takes a little while to load.
