The venom-delivering spur is found only on the male's hind limbs. 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]

The platypus doesn’t fit into any particular category: it’s a mammal, but it lays eggs like a reptile. ... The Platypus’s Painfully Venomous Spurs. A platypus typically measures 14.5 to 25 ...
The calcaneus spur found on the male platypus' hind limb is used to deliver venom. Spurs are uncommon in mammals. The male platypus has well developed spurs on the heels of its hind feet. The spurs are hollow and connected to a venom gland, allowing the platypus to deliver a very painful kick both in mating competitions and as a defense. [22]
The calcareous spur found on the male platypus's hind limb is used to deliver venom. Both male and female platypuses (Ornithorhynchus anatinus) hatch with keratinised spurs on the hind limbs, although the females lose these during development. The spurs are connected to the venom-producing crural glands, forming the crural system. During the ...
The platypus (Ornithorhynchus anatinus), [4] sometimes referred to as the duck-billed platypus, [5] is a semiaquatic, egg-laying mammal endemic to eastern Australia, including Tasmania. The platypus is the sole living representative or monotypic taxon of its family Ornithorhynchidae and genus Ornithorhynchus , though a number of related species ...
Like other monotremes, the platypus senses prey in cloudy water through electrolocation. The male platypus has a spur on the hind foot that delivers an extremely painful venom, making it one of the few species of venomous mammals. This platypus was photographed swimming in a creek near Scottsdale in Tasmania. Photograph credit: Charles J. Sharp
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.
