The platypus is generally nocturnal and crepuscular, but can be active on overcast days. [77] [78] Its habitat bridges rivers and the riparian zone, where it finds both prey and river banks to dig resting and nesting burrows. [78] It may have a range of up to 7 km (4.3 mi), with a male's home range overlapping those of three or four females. [79]

Platypus venom is likely retained from its distant non-monotreme ancestors, being the last living example of what was once a common characteristic among mammals. [2] Fossil records show that venom delivery systems were not sexually dimorphic in ancestral monotremes . [ 18 ]
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 a monotreme mammal that has secondarily acquired electroreception. Its receptors are arranged in stripes on its bill, giving it high sensitivity to the sides and below; it makes quick turns of its head as it swims to detect prey.
