The fictional character Knuckles the Echidna from Sonic the Hedgehog is a red short beaked echidna who possesses superhuman strength. The short-beaked echidna is an iconic animal in contemporary Australia, notably appearing on the five-cent coin (the smallest denomination), [122] and on a $200 commemorative coin released in 1992.

Ornithorhynchoidea is a superfamily of mammals containing the only living monotremes, the platypus and the echidnas, as well as their closest fossil relatives, to the exclusion of more primitive fossil monotremes of uncertain affinity.

This is similar to the platypus, which has 40,000 electroreceptors on its bill, but the long-beaked echidna has only 2,000, while the short-beaked echidna, which lives in a drier environment, has no more than 400 at the tip of its snout. [8] Echidnas have short, strong limbs with large claws, and are powerful diggers.
The Ornithorhynchidae / ɔːr ˌ n ɪ θ ə ˈ r ɪ ŋ k ɪ d iː / are one of the two extant families in the order Monotremata, and contain the platypus and its extinct relatives. The other family is the Tachyglossidae, or echidnas.
The echidna spurs are vestigial and have no known function, while the platypus spurs contain venom. [42] Molecular data show that the main component of platypus venom emerged before the divergence of platypus and echidnas, suggesting that the most recent common ancestor of these taxa was also possibly a venomous monotreme.
The Tasmanian short-beaked echidna (Tachyglossus aculeatus setosus) is a subspecies of short-beaked echidna endemic to Tasmania. [1] It was first described by Étienne Geoffroy Saint-Hilaire in 1803 as Echidna setosa, [1] [2] from two specimens, one of which was found in or near Bruny Island. [1] Jackson and others (2021) [3] review the ...
