Australian Echidna. An egg-laying mammal covered in spines with a tubular snout accommodating a long mobile tongue for lapping up ants and termites. The single egg is incubated for about 10 days in the mother’s abdominal pouch, and then suckles for 3 months, taking about 12 months to attain adulthood. Affectionately known as the Spiny Anteater it is a primitive mammal that lives in both Australia and New Guinea. It is a solitary animal that burrows. When it is attacked, the echidna will burrow into the ground.
