Nowadays any close contact with the animal is rare and restricted to biologists, zookeepers and anglers (who occasionally catch them in fishing lines or nets).[1]. By contrast, venoms evolved for defense, offenseor both. The function of defensins is to cause lysis in pathogenic bacteria and viruses, but in platypuses, they also are formed into venom for defense. 1998b;36(6):84757.

With two layers of fur for insulation and waterproofing, platypuses use their fur to trap a layer of air next to their skin so they can remain buoyant and dry when theyre underwater, which they are a lot. [1] To explain the rarity of venom delivery in Mammalia, Mark Dufton of the University of Strathclyde has suggested that modern mammalian predators do not need venom because they are able to kill quickly with their teeth or claws, whereas venom, no matter how sophisticated, requires time to disable prey. Most derive from perfectly normal enzymes. 2006;51(1):111. You may also want to read about animals that lay eggs. 2002a;40(6):7119.

However, other scientists have questioned this conclusion given that many living non-venomous mammals also have deep grooves down the length of their canines (e.g., many primates, coatis and fruit bats), suggesting that this feature does not always reflect an adaptation to venom delivery. They are one of the very few mammals that use electroreception, aka the ability to sense the electricity created by the movement of muscles.
