The western long-beaked echidna is an egg-laying mammal. Unlike the short-beaked echidna, which eats ants and termites, the long-beaked species eats earthworms.The long-beaked echidna is also larger than the short-beaked species, reaching up to 16.5 kilograms (36 lb); the snout is longer and turns downward; and the spines are almost indistinguishable from the long fur.
