What is the effect of platypus venom?
Although platypus venom has a broadly similar range of effects and is known to consist of a similar selection of substances to reptilian venom, it appears to have a different function from those poisons produced by lower vertebrates; its effects are not life-threatening but nevertheless powerful enough to cause serious impairment to the victim , which can lead to temporary paralysis. It is not used as a method of disabling nor killing prey, and although it acts as a defensive mechanism, only males produce venom. Since production rises during the breeding season, it is theorised that the venom is used as an offensive weapon to assert dominance and to control territory during this period. While the platypus may use this characteristic for offensive mating purposes, they may have also adapted it for defensive techniques. Crocodiles, Tasmanian devils, and raptors are known local predators to the platypus, all of which can be impacted by the venom.

Where is the venom gland located?
The venom is produced in the crural glands of the male, which are kidney-shaped alveolar glands located in the upper thigh connected by a thin-walled duct to a calcaneus spur, or calcar, on each hind limb. 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. 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 would allow. The spur normally lies flat against the limb but is raised when required.

They are extremely energetic, feeding almost continuously while in the water, shoveling through streambed debris with their flat bills as they hunt for larval insects and freshwater crustaceans (a favourite food). The platypus uses its sophisticated electromechanical system to detect minute electrical signals given off by the muscles of its prey. After feeding, it retires to its burrow, the entrance of which is large enough to admit only the platypus and serves to squeeze excess moisture from the fur.
