The platypus is the sole living representative or monotypic taxon of its family Ornithorhynchidae and genus Ornithorhynchus , though a number of related species ...
This contrasts with the modern platypus, where adults are entirely toothless. It has been theorized that the loss of teeth in the platypus was a geologically recent event, occurring only in the Pleistocene (after over 95 million years of tooth presence in the ornithorhynchid lineage) after the migration of the rakali ( Hydromys chrysogaster ...
The platypus has an average body temperature of about 31 °C (88 °F) rather than the averages of 35 °C (95 °F) for marsupials and 37 °C (99 °F) for placentals. [ 30 ] [ 31 ] Research suggests this has been a gradual adaptation to the harsh, marginal environmental niches in which the few extant monotreme species have managed to survive ...
The platypus is one of the few living mammals to produce venom. The venom is made in venom glands that are connected to hollow spurs on their hind legs; it is primarily made during the mating season. [1] While the venom's effects are described as extremely painful, it is not lethal to humans.

Platypus quercivorus, the oak ambrosia beetle, is a species of weevil and pest of broad-leaved trees. [2] This species is most commonly known for vectoring the fungus responsible for excessive oak dieback in Japan since the 1980s. [ 3 ]

Rheobatrachus, whose members are known as the gastric-brooding frogs or platypus frogs, is a genus of extinct ground-dwelling frogs native to Queensland in eastern Australia. The genus consisted of only two species, the southern and northern gastric-brooding frogs, both of which became extinct in the mid-1980s.
