The Echidna found in Australia is the Short-beaked Echidna and along with the Platypus are the only members of the monotreme family which are Mammals that lay eggs and produces milk for its young. Echidnas (pronounced "E-kid-na") sometimes referred to as Spiny Anteaters resemble the Hedgehog and the Porcupine in that they are covered by sharp spines. The Echidna is found all over Australia and can survive a range of temperatures and habitats Though mostly nocturnal, in mild weather they can be seen during the day, but if the weather is extreme (either very cold or hot) Echidnas will stay in shelter. (under rocks, fallen timber or burying themselves in the ground) An Echidnas body is covered with 2 types of hair. A "normal" short coarse hair to keep them warm and long sharp spines each being a single hair but hard(similar to our fingernails in composition) The colouring and length of their "normal" hair differs wildly across Australia depending on climate and habitat) In size Echidnas are between 35 - 45 cms long and weigh anything between 2-7 kg. They Echidna has a pointy snout and an extremely long sticky tongue to catch ants and termites The Echidnas feet have sharp claws for digging and though like the Platypus the male has a spur on its ankle, it is not poisonous They make a sniffing noise as they search for food Echidnas are mammals; they have hair and suckle their young on milk . They are warm blooded. The Australian Short-beaked Echidna is one of three surviving monotremes. Monotremes are a special group of mammals which lay eggs. There are three monotremes living on the planet today: the platypus, the short beaked echidna (just called echidna) and the long beaked echidna . Today, the long beaked echidna lives only on the island of Papua New Guinea. Ancestors of echidnas roamed the planet with the dinosaurs. Dinosaurs died out but monotremes are still alive. The echidna eats lots of invertebrates besides ants and termites. Echidnas are active both day and night. Echidnas are solitary living except during the breeding season. Echidnas breed during the winter. An echidna lays only one single egg . A female echidna carries her young in her pouch. When the young starts growing spines, she digs a special nursery burrow put it in. Echidnas can live to be 50 years old .
