Echidna's are one of my favourite Australian marsupials.
The last time I saw one I think was several years ago, when we had a holiday on Kangaroo Island off South Australia. We saw one walking along beside the unmade road.
As soon it heard the car it curled up in a defence mechanism with all it's spiky spines showing. If you want to read more about the life of an echidna check out this site
