Found in eastern Australia, platypi are special mammals.  They are 1 of 2 monotremes; meaning instead of giving birth to their young, they lay eggs.  They are fantastic divers – spending up to 12 hours in the water each day.  Underwater their flat tail stabilises them & their webbed feet aid swimming.  They have 2 layers of fur; a woolly undercoat with a longer, dense fur on top.   These 2 layers trap air, keeping the platypus warm & dry.
