Sort of like the horns and antlers that bulls, male deer and male moose may use to fight with each other. The spurs are designed to disable other platypuses in mating fights, but they have also been used to attack humans and dogs. If a tiger were to cross paths with a king cobra in such a way as to be able to bite the tiger and hang on however, their venom is strong enough to kill the cat. The poison is used to ward off adversaries. Only male platypuses produce venom. A small semi-aquatic, egg laying mammal with a bill, flat tail and poison spurs. [4] The spur normally lies flat against the limb but is raised when required. As luck would have it, however, platypus poison can actually be of beneficial use to humans as it may prove useful in the treatment of diabetes mellitus. The platypus is one of the few living mammals to produce venom. Platypuses can be captured in cage traps and trained into cheap exotic pets. [4] Coagulating effects have been seen during experiments on laboratory animals, but this has not been observed consistently. Dog fatalities as a result of platypus stings have been documented. Keywords: bioactive molecules; chemical ecology; mass spectrometry; mammalian venom; natural products. Venom is usually associated with insect stings and reptile bites. More about Kevin and links to his professional work can be found at www.kemibe.com. While the venom is not fatal to humans, it results in swelling around the affected area and excruciating pain that can temporarily incapacitate its victim. A newborn platypus is called a baby. Platypus venom can paralyze small animals (such as a rival male) and, although it is not quite potent enough to do the same to a human, an attack is surprisingly painful and incapacitating. The platypus is one of only five mammals that produce venom. [1] The OvDLPs are related to, though distinct from, those involved in reptilian venom production. The males of the extraordinary semi-aquatic mammal - one of the only kind to lay eggs - have venomous spurs on the heels of their hind feet. The platypus is a truly unusual creature in multiple ways, one of many storied and whimsical-looking animals originating in Australia. [2], 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. The venom is produced in the crural glands of the male and then connected to a spur on each hind limb with the help of thin-walled ducts. 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 … Platypus, an egg-laying mammal, have venomous spurs on the heels of their hind feet attached to a venom-secreting gland. Platypus venom isn't designed to destroy or kill -- it's only meant to cause pain. Many archaic mammal groups possess similar tarsal spurs, so it is thought that, rather than having developed this characteristic uniquely, the platypus simply inherited this character from its antecedents. It could be semantically argued that "The venom-delivering spur is found only on the male's hind limbs." Platypus venom has at least 25 chemical components, including a protein that lowers blood pressure (causing shock); digestive enzymes that dissolve body tissue, helping venom spread; and a compound that acts on the nerve cells that register pain. Once the venom hits their attackers eyes, others usually retreat as it stings and burns. The venom is produced in a small gland on the inside of the male animal's thigh, and delivered via a sharp, curved spike or spur. 36 Tonkin MA, Negrine J Wild platypus attack in the antipodes. But figuring out what’s in platypus venom is more than just biology navel-gazing. You should avoid handling and being around the animal during mating season. Like egg-laying, venom production is a very rare trait among mammals, being otherwise restricted mainly to snakes, spiders, insects and certain marine creatures. A sting produces a swelling around the wound which extends up the affected limb. For over two centuries, the platypus (Ornithorhynchus anatinus) has been constructed and categorized in multiple ways. [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 would allow. They have venom sacks, but these sacks only appear during the mating season. The venom … Although it isn't lethal for humans, it can cause intense pain. The pain … Platypus venom is a clear, slightly sticky fluid containing different active compounds than those found in snake venoms. The platypus is probably the most iconic aquatic Australian mammal; many advertisements for pools, swimming lessons and fishing gear will use one. Ms Whittington says the venom is injected by the male platypus, which has sharp spurs on each hind leg that can spring into action when the animal is attacked. [7] This appears to be an example of convergent evolution of venom genes from existing immune system genes (defensins). Venom is released much more frequently during the mating season. [1] While the venom's effects are described as excruciatingly painful, it is not lethal to humans. Third, the venom doesn’t kill other platypuses (though it can kill large dogs if they attack during platypus breeding season). This has created an interesting tug-of-war between the dual functions of GLP-1 in the gut and venom of platypus. cated that platypus venom contains tissue kallikrein-like protease(s), and its proteolytic activ-ity might synergistically contribute to toxicity through the specific cleavage of other venom constituents.
