Did You Know?
There are two species of echidna. Both are egg-laying mammals that are stocky and virtually tailless. They have strong-clawed feet and spines on the upper part of a brownish body. The snout is narrow and the mouth is small, with a tongue that is long and sticky for feeding on termites and ants, their chief food. New Guinea echidnas are 18–31 in (45–78 cm) long and piglike. Valued for their meat, they are declining in numbers. Echidnas of Australia and Tasmania are 14–21 in (35–53 cm) long. Echidnas exude milk from mammary openings on the skin, and the young lap it up.
