Echidnas/ɨˈkɪdnə/, sometimes known as spiny anteaters, belong to the familyTachyglossidae in the monotreme order of egg-laying mammals. The four extant species, together with the platypus, are the only surviving members of that order and are the only extant mammals that lay eggs.Although their diet consists largely of ants and termites, they are no more closely related to the true anteaters of the Americas than to any other placental mammal. They live in Australia and New Guinea. The echidnas are named after a monster in ancient Greek mythology.
Male echidnas have a four-headed penis. During mating, the heads on one side “shut down” and do not grow in size; the other two are used to release semen into the female’s two-branched reproductive tract. The heads used are swapped each time the mammal copulates. When not in use, the penis is retracted inside a preputial sac in the cloaca. The male echidna’s penis is 7 centimeters long when erect, and its shaft is covered with penile spines.
