Short-beaked echidna

Overview

The short-beaked echidna has a rounded spine-covered back, short digging legs and a slender tubular snout. Fur fills the spaces between stout spines. The snout and claws help it reach insects, which a sticky tongue collects.

Australian Museum describes habitats from woodland and heath to grassland and dry country. Its current account covers Australia including Tasmania; the museum’s older natural-history treatment also records lowland New Guinea. Geographic populations should not be treated as a single uniform local ecology.

Egg laying and milk feeding occur in the same life cycle. A young animal initially develops in the mother’s temporary pouch, then occupies a nursery burrow as its spines develop. Its monotreme relationship to the platypus concerns ancestry and reproduction, while their adult feeding structures differ substantially.

Origins & earliest records

A living monotreme in Tachyglossidae, rather than a hedgehog or a porcupine. The egg-laying condition is a retained mammalian reproductive pattern, not evidence that this living species has remained unchanged through geological time.

Evidence & interpretation

The museum account supports anatomy and development and identifies collection specimen AM M.6641. The older museum publication supplements New Guinea distribution; its outdated count of other echidna species is not adopted.
