Echidna
Echidnas are egg-laying monotreme mammals, also known as spiny anteaters.
Echidnas are egg-laying monotreme mammals native to Australia and New Guinea. Also known as spiny anteaters, they are among the few living mammals that lay eggs.
What it is
Echidnas belong to the family Tachyglossidae in the order Monotremata. They have spines (modified hairs), a long snout, and a sticky tongue. The group includes one short-beaked species and three long-beaked species.
Where they live and what they eat
Echidnas are found in Australia, Tasmania, and New Guinea. Long-beaked species are mainly associated with New Guinea. Their diet consists primarily of ants, termites, worms, and other small invertebrates, which they capture with their long sticky tongue.
How they reproduce
As monotremes, echidnas lay eggs rather than giving live birth. Females typically lay a single leathery egg per breeding cycle. This reproductive method is shared only with the platypus among living mammals.
In short
- Echidnas are monotremes, a rare group of egg-laying mammals.
- They are covered in spines and have a long snout and sticky tongue.
- Four living species: one short-beaked, three long-beaked.
- Found in Australia, Tasmania, and New Guinea.
Echidnas have no native range in Canada, but they are a notable example of mammalian evolution and are often used in Canadian wildlife and biology education as an example of monotremes.
