If this is the case with its own species, then perhaps the venom evolved along with the mating systems to be a tool for social dominance. 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 non-mammalian species: its effects are not life threatening but nevertheless powerful enough to seriously impair the victim. Platypus feet are flat; in fact, their name comes from the Latin for "flat foot.". 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. Much like Monkeys, Penguins and Pandas, the duck-billed platypus has achieved a certain level of popularity. This has created an interesting tug-of-war between the dual functions of GLP-1 in the gut and venom of platypus. Shrews are the exact opposite of reptiles: they need to eat a lot, and often, just to stay alive. Feb 14, 2019 - Explore Kriti Roongta's board "Platypus" on Pinterest. Nevertheless, since 1797, naturalists and biologists have pursued two recurring obsessions. Although the makeup of platypus venom has a broadly similar range of effects to that of snake venom, it appears to have a different function from those poisons produced by non-mammalian species: its effects are non-life threatening but nevertheless powerful enough to seriously impair the victim. Interestingly, a male platypus injects venom into another male platypus while fighting for the female’s attention. Unlike snake venom, there appears to be no necrotising component in the platypus's venom – although some muscle wastage has been observed in cases of envenomation in humans, it is likely that this is due to the inability to use the limb while the effects of the venom persist. The fear of attacks from pit bulls has led to bans on the breed in many cities. This is the only known such example in mammalian systems.[8]. It is rather complex and has about 88 different toxins, some of which inhibit blood clotting, disrupt cell membranes, and activate pain receptors. Whilst agonising, the venom of the male platypus is quite fascinating. As a result, platypus venom is only produced during breeding season, and outside of that season the male platypus rarely if ever uses its spur. Were mammals originally venomous?, Acta Palaeontologica Polonica 51 (1), 2006: 1-11, "Defensins and the convergent evolution of platypus and reptile venom genes", "Genome analysis of the platypus reveals unique signatures of evolution", Platypus venom could hold key to diabetes treatment, https://en.wikipedia.org/w/index.php?title=Platypus_venom&oldid=988236121, All Wikipedia articles written in Australian English, Creative Commons Attribution-ShareAlike License, This page was last edited on 11 November 2020, at 22:48. It's possible that the platypus might view you as a threat and attack with its spurs, though this is unlikely. However, platypus venom is only produced by males, and is used to attack other males to induce hypoglycaemic shock and affect their ability to mate. Kevin Beck holds a bachelor's degree in physics with minors in math and chemistry from the University of Vermont. However, it can be treated successfully using drugs which act to block nerve transmission. also conveys that message, but it doesn't naturally read that way. That's kind of the approach evolution used when designing this odd creature's venom; scientists have just determined that the venom contains over 80 different toxins in 13 different classes. [5][9] A clinical report from 1992 showed that the severe pain was persistent and did not respond to morphine. However, it can be treated successfully using drugs which act to block nerve transmission. In humans, this venom causes pain and swelling, increased sensitivity to pain in general (called hyperalgesia), hyperventilation, low blood oxygen and convulsions, depending on the dose received. Some of the most venomous animals (the ones with the most potent venom) include the yellow-lipped sea krait (a sea snake), box jellyfish, sea wasp jellyfish, blue-ringed octopus, reef stonefish, the inland taipan and cone shells. Rattlesnakes, vipers and some spiders use hemotoxins. WILD PLATYPUS ATTACK IN THE ANTIPODES A case report M. A. TONKIN and J. NEGRINE From the Department of Hand Surgery, Royal North Shore Hospital, Sydney, Australia The platypus (ornithovhynchus anatinus) is a furry duck-billed mammal that inhabits the waterways of eastern Australia. 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 … In humans, this venom causes pain and swelling, increased sensitivity to pain in general (called hyperalgesia), hyperventilation, low blood oxygen and convulsions, depending on the dose received. These included 7 genes that had greater than 500 Illumina reads mapping to them and which therefore appear to be highly expressed.
