The Spiny Echidna
The only other animal that can parallel this mixture of primitive features is the spiny ant-eater called Echidna which taxonomists renamed Tachyglossus (swift-tongued). These animals are spiny with a long tube-like snout that has no teeth but does possess a long tongue which flicks out to catch insects. Its front legs are equipped with long digging claws. At the beginning of each mating season the female develops a small pouch into which she later transfers her single egg. The mammary glands discharge directly into the pouch and the milk is sucked of the hairs.
