The Short-Beaked Echidna is the only native Echidna to Australia - the other 3 extant echidnas are native to Niu Gini! Thank you for the etymology! I had no idea they painted Ekhidna as such a gross sea-beast 😂
I studied the skeletal structure of T. aculeatus! They have a pectoral girdle that is really similar to the therapsids (mammal-like reptiles from the Permian/Triassic)! Shows how old of a species monotremes are! Their humerus is lateral to the body, giving them that waddle, and their tibia and fibula are “backwards” compared to mammals causing their hind feet to point caudally!
