Is that the Niu Gini one that’s recently been re-discovered? I know they’ve got long beaked echidnas, but I think there’s been some developments on the short-beaked side quite recently.

He he, the actual word echidna is NOT an indigenous word - it comes from greek mythology and is the name of a goddess of chaos. quote below from theoi.com

“EKHIDNA (Echidna) was a monstrous she-dragon (drakaina) with the head and breast of a woman and the tail of a coiling serpent. She probably represented the corruptions of the earth–rot, slime, fetid waters, illness and disease.

Ekhidna was sometimes equated with Python “the Rotting One”, a dragon born of the fetid slime left behind by the great Deluge. Others name her the Tartarean lamprey, and place in her to the dark, swampy pit of Tartaros beneath the earth. Hesiod, makes her a daughter of monstrous sea-gods, and presumably associates her with rotting sea-scum and fetid salt-marshes.

Ekhidna was the consort of Typhoeus–a monstrous, multi-headed storm-giant who challenged Zeus to the throne of heaven. Together they spawned a host of terrible monsters to plague the earth including the Khimaira (Chimera), Kerberos (Cerberus), the Hydra, Sphinx and the Drakon Hesperios (Hesperian Dragon).

Four other closely related she-dragons were the Argive Ekhidna and Poine (Poena), the Tartarean Kampe (Campe), and the Phokian Sybaris.”
