Female platypuses, in common with echidnas, have rudimentary spur buds that do not develop (dropping off before the end of their first year) and lack functional crural glands. [3] The spur is attached to a small bone that allows articulation; the spur can move at a right angle to the limb allowing a greater range of attack than a fixed spur ...
Male platypuses have sharp spurs on their back legs shaped like a canine tooth. These hollow spurs measure 0.59 to 0.71 inches long and connect to crural glands in the animal’s upper thighs.
The spurs have enough strength to support the weight of the platypus, which often hangs from the victim, requiring assistance for removal. Most of the evidence now supports the proposition that the venom system is used by males on one another as a weapon when competing for females, taking part in sexual selection .

Venoms have adapted to serve a wide variety of purposes. Their intended effects can range from mild fleeting discomfort to paralysis and death, and they may be highly selective in which species they target, often making them harmless to all but a few specific organisms; what may be fatal to one species may be totally insignificant to another ...
[5] [6] It may be distinguished by the shape of its dorsal pereon and pleon segments, which are sharp in T. platypus, and round in T. depressus. [5] Only the final (7th) segment of the pereon and pleon segments 1 and 2 have these tooth-like projections. The only other distinguishing characteristic is a broad rostrum that is longer than the head ...
