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.
A marsupial has a short gestation period, typically shorter than its estrous cycle, and gives birth to an underdeveloped newborn that then undergoes further development; in many species, this takes place within a pouch-like sac, the marsupium, located in the front of the mother's abdomen.
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 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 ...
Newer taxonomy is frequently based on cladistics instead, giving a variable number of major "branches" of the tetrapod family tree. As is the case throughout evolutionary biology today, there is debate over how to properly classify the groups within Tetrapoda.
The monotremes (egg laying mammals) represent the order of extant mammals most distantly related to humans. The platypus (Ornithorhynchus anatinus) is indigenous to eastern Australia; the short-beaked echidna (Tachyglossus aculeatus) is indigenous to Australia and Papua New Guinea; whereas the long-beaked echidna (Zaglossus bruijni) is restricted to Papua New Guinea and Irian Jaya.
