Western long-beaked echidna

It may not look very appetizing due to its porcupine-like spines, but the western long-beaked echidna is critically endangered primarily because it is hunted for food in its native home of New Guinea. It's possible the species may already be gone — none have been recorded since the 1980s. Echidnas, along with the platypus, are the only mammals in the world that lay eggs, making their existence important for understanding mammalian evolution.
