The Echidna is a animal that burrows. When it is attacked, the echidna will curl itself into a ball using its spines as defence. The echidna's spines cover the top of its body. Their nose is very sensitive, they use this to find food, then they use their long sticky tongue to catch ants, worms and other insects. The Echidna's average wieght is 5 pounds.

"The female echidna normally lays one egg, although it can occasionally lay two or even three. She keeps the egg warm for about ten days in a temporary pouch on her abdomen. When the baby echidna hatches, it begins suckling milk inside the pouch, where it will live until its spines begin to appear. At that point, the mother puts her baby in a sheltered place and goes about her business."--- www.americazoo.com
