Question: are echidnas and hedgehogs related?
Answer: Echidna Quills Echidnas or “spiny anteaters” (Tachyglossidae) are obscure, medium-sized mammals (up to 16 kg) from Australia and New Guinea. Although they superficially resemble a cross between the anteaters of South America and the hedgehogs of Eurasia and Africa, they are not closely related to either.
