Long-beaked Echidna (Tachyglossus bruijni), Papua New Guinea. A member of the order Monotremata, these are egg-laying mammals. The Long-beaked Echidna can weigh 13-35 lbs. It has spines of varying length interspersed with fur on its back, sides and tail. The snout is tubular with a very small mouth through which the long tongue can be rapidly extruded and retracted. Its lack of teeth is compensated for by rows of 'spikes' (horny teeth-like projections on the tongue). It is found in humid montane forests on New Guinea and is mainly nocturnal, feeding on earthworms and other invertebrates on the forest floor. It shelters in burrows, hollow logs, or cavities under roots or rocks. The female usually lays one egg into a pouch, from which the baby hatches about 10 days later. The baby spends the next six months in the mother's pouch. IUCN listed in 1994: Endangered.
