Watch an Echidna (sometimes known as spiny ant eater) crossing Interlude creek at Rafters Basin. While a bit clumsy climbing over rocks as soon as it hits the water it moves very efficiently using the snout as a snorkel.
Echidnas and platypuses are the only egg-laying mammals, the monotremes. Their elongated and slender snout functions as both mouth and nose and has electro sensors to find food. The platypus has about 40,000 electroreceptors on its bill where as the echidna has no more than 400 at the tip of its snout.
Echidnas are powerful diggers and use their long sticky tongue to lick up ants as they go. They feed their young on milk and their average life span is 15 years.
