What Are the Differences Between Echidnas and Hedgehogs? The biggest difference between the Echidna and the Hedgehog is that they belong to two different species. They have different facial features, and the Hedgehog is a bit larger than the Echidna but has a rounder body that makes them look more compact.
Furthermore, why do echidnas have 4 heads?
But in short-beaked echidnas, the cavernosum was merged while the spongiosum remained separate. This separate spongiosum tissue is what allows echidnas to erect each half, or pair of heads, independently from the other, the researchers said.
Moreover, is an echidna a porcupine?
Although people commonly use the term ‘porcupine’ for our echidnas, they are definitely not the same animal. Although they are both spiny, echidnas don’t release their spines to defend themselves as do porcupines.
Are echidnas poisonous?

Can echidna be a pet?

Can echidnas hurt dogs?
Dogs and cats with echidnas
