The name echidna refer to any member from three species of native ant-eating monotremes. Echidnas are unusual in that they are egg-laying mammals, they are equipped with spines (for protection) and have electro sensors in their bill. Baby echidnas are called puggles.
Echidnas, sometimes known as spiny anteaters, are a type of egg-laying mammal. The four extant species, together with the platypus, are the only surviving members of that order and are the only extant mammals that lay eggs. Although their diet consists largely of ants and termites, they are no more closely related to the true anteaters of the Americas than to any other placental mammal. They live in Australia and New Guinea. The echidnas are named after a monster in ancient Greek mythology.
This little echidna is lucky to be alive after being found wandering down the middle of the street in Victoria, Australia. Megan Wilson first spotted the spiky creature and scooped him up and took him to the Healesville Animal Sanctuary.
