Monotremes aren\u2019t viviparous (live-bearing) but oviparous, so young are sustained by yolk until they hatch. Hatchlings (nicknamed puggles) must lick the milk secreted from a mother\u2019s skin, as females don\u2019t have nipples. There are only five living species: four kinds of echidna plus the platypus \u2013 a semi-aquatic creature that looks like a <a href=\"https:\/\/www.discoverwildlife.com\/animal-facts\/mammals\/facts-about-eurasian-beavers\">beaver<\/a> and a duck\u2019s love-child.\u00a0<\/p><p>Weirdest animals: meet the weird freaks and oddballs of the natural world<\/p><p>Monotremes have just one orifice or \u2018cloaca\u2019 for urination, intercourse and defaecation, hence the name \u2013 monotreme comes from the Greek for \u2018single opening\u2019. It\u2019s one of several reptilian or bird-like traits that were probably present in the common ancestor of all living mammals. <\/p><p>But while monotremes are considered primitive, they have some sophisticated features too. Their snout (or beak\/bill) can sense electricity to detect prey, for example, and platypus males have venomous leg spurs.<\/p><h2 class=\"wp-block-heading\"><strong>Where are monotremes<\/strong> <strong>found?<\/strong><\/h2><figure class=\"wp-block-video\"><video controls=\"\" src=\"https:\/\/c02.purpledshub.com\/uploads\/sites\/62\/2024\/09\/echidna.mp4\"\/><figcaption class=\"wp-element-caption\">Getty video<\/figcaption><\/figure><p> Monotremes are found in Australia and New Guinea. This distribution of monotremes reflects the fact that Australia and South America were once connected as a supercontinent, Gondwana.<\/p><h2 class=\"wp-block-heading\"><strong>Why do <strong>monotremes<\/strong><\/strong> <strong>produce<\/strong> <strong>eggs?<\/strong><\/h2><p>A complex placenta and long pregnancy has benefits, such as protecting a baby from predators and extreme temperatures. But carrying a foetus for several months has costs: it\u2019s exhausting for females and makes mother and child vulnerable to attack or injury. <\/p><p>Pregnancy also causes conflicts over resources and triggers immune responses because one individual is a <a href=\"https:\/\/www.discoverwildlife.com\/animal-facts\/biggest-parasite\">parasite<\/a> within the other\u2019s body. So in certain environments, like Australia\u2019s harsh habitats, natural selection may have favoured mammals that can abandon an egg to survive, until conditions are better for their reproductive success.\u00a0<\/p><h2 class=\"wp-block-heading\"><strong>How many monotremes &#8211; egg laying mammal &#8211; species are there?<\/strong><\/h2><p>There only five species of <strong><strong>monotremes<\/strong><\/strong> today, four species of echidna and the duck-billed platypus<\/p><ul><li><a href=\"https:\/\/www.discoverwildlife.com\/animal-facts\/mammals\/winston-churchill-platypus\">Why Winston Churchill was given a duck-billed platypus?<\/a><\/li><\/ul> <\/body><\/html>\n<hr class=\"no-tts wp-block-separator\"\/>","protected":false},"excerpt":{"rendered":"<p>All you need to know about monotremes, weird egg-laying mammals <\/p>\n","protected":false},"author":24,"featured_media":41902,"template":"","categories":[1],"acf":{"readingTimeMinutes":"2"},"uagb_featured_image_src":{"full":["https:\/\/c01.purpledshub.com\/uploads\/sites\/44\/2024\/09\/monotremes-meet-natures-oddballs-that-bridge-the-evolutionary-gap-between-mammals-and-reptiles.jpg",2121,1414,false],"thumbnail":["https:\/\/c01.purpledshub.com\/uploads\/sites\/44\/2024\/09\/monotremes-meet-natures-oddballs-that-bridge-the-evolutionary-gap-between-mammals-and-reptiles-150x150.jpg",150,150,true],"medium":["https:\/\/c01.purpledshub.com\/uploads\/sites\/44\/2024\/09\/monotremes-meet-natures-oddballs-that-bridge-the-evolutionary-gap-between-mammals-and-reptiles-300x200.jpg",300,200,true],"medium_large":["https:\/\/c01.purpledshub.com\/uploads\/sites\/44\/2024\/09\/monotremes-meet-natures-oddballs-that-bridge-the-evolutionary-gap-between-mammals-and-reptiles-768x512.jpg",768,512,true],"large":["https:\/\/c01.purpledshub.com\/uploads\/sites\/44\/2024\/09\/monotremes-meet-natures-oddballs-that-bridge-the-evolutionary-gap-between-mammals-and-reptiles-1024x683.jpg",800,534,true],"1536x1536":["https:\/\/c01.purpledshub.com\/uploads\/sites\/44\/2024\/09\/monotremes-meet-natures-oddballs-that-bridge-the-evolutionary-gap-between-mammals-and-reptiles-1536x1024.jpg",1536,1024,true],"2048x2048":["https:\/\/c01.purpledshub.com\/uploads\/sites\/44\/2024\/09\/monotremes-meet-natures-oddballs-that-bridge-the-evolutionary-gap-between-mammals-and-reptiles-2048x1365.jpg",2048,1365,true]},"uagb_author_info":{"display_name":"importmanagerhub@sprylab.com","author_link":"https:\/\/c01.purpledshub.com\/bbcwildlife\/author\/importmanagerhubsprylab-com\/"},"uagb_comment_info":0,"uagb_excerpt":"All you need to know about monotremes, weird egg-laying mammals","_links":{"self":[{"href":"https:\/\/c01.purpledshub.com\/bbcwildlife\/wp-json\/wp\/v2\/rss_feed\/41901"}],"collection":[{"href":"https:\/\/c01.purpledshub.com\/bbcwildlife\/wp-json\/wp\/v2\/rss_feed"}],"about":[{"href":"https:\/\/c01.purpledshub.com\/bbcwildlife\/wp-json\/wp\/v2\/types\/rss_feed"}],"author":[{"embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcwildlife\/wp-json\/wp\/v2\/users\/24"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcwildlife\/wp-json\/wp\/v2\/media\/41902"}],"wp:attachment":[{"href":"https:\/\/c01.purpledshub.com\/bbcwildlife\/wp-json\/wp\/v2\/media?parent=41901"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcwildlife\/wp-json\/wp\/v2\/categories?post=41901"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
