The echidnas have a covered robust body of a mixture of fur and prickles, digger members, have a small mouth, with fine a jaw, do not have teeth but a long sticking language with which they catch Termite S and others Arthropodes.
The echidnas generally live as recluses.

Naked with the birth, the young remainder inside this one during 6 to 8 weeks, licking the Milk which runs out of the glands mammaires emerging in the pocket.
