belong to the family Tachyglossidae in the monotreme order of egg-laying mammals.The four extant species, together with the platypus, are the only surviving members of the order Monotremata and are the only living mammals that lay eggs.They have elongated and slender snouts that function as both mouth and nose.Like the platypus, they are equipped with electrosensors, but while the platypus has 40,000 electroreceptors on its bill, the long-beaked echidna has only 2,000 electroreceptors, and the short-beaked echidna, which lives in a drier environment, has no more than 400 located at the tip of its snout.Although they have a way to protect themselves, the echidnas still face many dangers.Some predators include wild cats, foxes, domestic dogs and goannas.The echidnas' ears are slits on the sides of their heads that are usually unseen due to the fact that they are blanketed by their spines.
Superficially, they resemble the anteaters of South America and other spiny mammals such as hedgehogs and porcupines. There have been several reports of albino echidnas, their eyes pink and their spines white.
Contrary to previous research, the echidna does enter REM sleep, but only when the ambient temperature is around 25 °C (77 °F).
At temperatures of 15 °C (59 °F) and 28 °C (82 °F), REM sleep is suppressed. Echidna "puggle" (a) compared to various "joeys": Virginia Opossum (b), Gray short-tailed opossum (c), Eastern quoll (d), Koala (e), Brushtail possum (f) and Southern brown bandicoot (g). The mother digs a nursery burrow and deposits the young, returning every five days to suckle it until it is weaned at seven months.
Echidnas and the platypus are the only egg-laying mammals, known as monotremes.
The average lifespan of an echidna in the wild is estimated around 16 years.
