Although not true of every animal on this list (looking at you barrel-eye fish), the primary reason for an animal evolving to be see-through appears to be to avoid notice from predators.<\/p><p> By letting light shine through them, blurring their outlines, and blending in, these unconventional animals manage to avoid detection and increase their chances of survival. Read on to find out more about our favourite see-through, transparent animals.\u00a0<\/p><h2 class=\"wp-block-heading\" id=\"h-10-transparent-animals\">10 transparent animals<\/h2><h3 class=\"wp-block-heading\" id=\"h-glass-frogs\">Glass frogs<\/h3><figure class=\"wp-block-image size-full\"><figcaption class=\"wp-element-caption\">\u00a9 Jesse Delia<\/figcaption><\/figure><p>Native to Central American rainforests, <a href=\"https:\/\/www.discoverwildlife.com\/news\/glassfrogs-hide-blood-in-their-liver-to-boost-transparency\">glass frogs<\/a> (one of the <a href=\"https:\/\/www.discoverwildlife.com\/animal-facts\/amphibians\/wirdest-frogss\">world&#8217;s weirdest frogs<\/a>) are a family of frogs that have transparent bellies and chests. Their internal organs including their heart pumping blood and food moving through their digestive tract can be clearly seen through their skin.<\/p><p>This translucency does have an important purpose, in that it allows them to blend in more seamlessly with their surroundings. The clear skin underneath and on the legs paired with an\u00a0opaque green back acts\u00a0as a form of camouflage, blurring their outline and making them more difficult to spot on leaves. <\/p><p>Fascinatingly, it has recently been discovered that this clever camouflage goes even further, with glass frogs possessing the ability to strategically remove red blood cells from circulation when\u00a0needed, and\u00a0store them in their liver for a while. This makes them look even clearer and more see-through, as red blood cells are what give blood its vibrant colour.\u00a0<\/p><figure class=\"wp-block-video\"><video controls=\"\" src=\"https:\/\/c02.purpledshub.com\/uploads\/sites\/62\/2024\/06\/GettyImages-131557847.mp4\"\/><figcaption class=\"wp-element-caption\">Getty video<\/figcaption><\/figure><h3 class=\"wp-block-heading\" id=\"h-nbsp-sea-angel-gymnosomata-nbsp-suborder\">\u00a0Sea angel (<em>Gymnosomata\u00a0<\/em>suborder)<\/h3><figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"2121\" height=\"1414\" src=\"https:\/\/c02.purpledshub.com\/uploads\/sites\/62\/2024\/06\/Sea-angel-is-a-transparent-animal.jpg\" alt=\"Sea angel is a transparent animal\" class=\"wp-image-102627\"\/><figcaption class=\"wp-element-caption\">Getty images<\/figcaption><\/figure><p>Angelic as they may look, these curious creatures are\u00a0actually slugs! Sea slugs to be precise. Unlike many other sea slugs\u00a0that\u00a0can only crawl along the sea bottom, sea angels are able to freely swim through the water by flapping their transparent fleshy \u2018wings\u2019. <\/p><p>They are closely related to sea butterflies who have larger wings and often have shells. Despite their diminutive wings sea angels are much stronger swimmers, able to propel themselves through the water swiftly and gracefully. They are also formidable predators, feeding on unfortunate (and slow) sea butterflies primarily. When they come into contact with\u00a0prey\u00a0they grab them with tentacles protruding from their head and hook them in with specialised appendages, prising the sea butterflies out of their shell and into the angel\u2019s gut.\u00a0<\/p><figure class=\"wp-block-video\"><video controls=\"\" src=\"https:\/\/c02.purpledshub.com\/uploads\/sites\/62\/2024\/06\/GettyImages-1477344016.mp4\"\/><figcaption class=\"wp-element-caption\">Getty video<\/figcaption><\/figure><h3 class=\"wp-block-heading\" id=\"h-glasswing-nbsp-butterfly-greta-nbsp-oto\">Glasswing\u00a0butterfly (<em>Greta\u00a0oto)<\/em><\/h3><figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"2124\" height=\"1411\" src=\"https:\/\/c02.purpledshub.com\/uploads\/sites\/62\/2024\/06\/Glasswing-butterly-is-a-transparent-animal.jpg\" alt=\"Glasswing butterfly is a transparent animal\" class=\"wp-image-102630\"\/><figcaption class=\"wp-element-caption\">Getty images<\/figcaption><\/figure><p>Similarly to glass frogs, the transparent wings of the beautiful (and aptly named)\u00a0glasswingbutterfly allow them to camouflage and better avoid predators. During flight,\u00a0they blend into the background and are very hard to spot. Such perfect transparency is achieved through a combination of factors.\u00a0<\/p><p>Firstly,\u00a0their wings lack the densely packed pigmented scales that are usual in butterflies. Instead, the see-through membrane of their wings is overlaid with sparse, spindly scales leaving gaps for light to pass through. <\/p><ul><li><a href=\"https:\/\/www.discoverwildlife.com\/animal-facts\/insects-invertebrates\/butterfly-vs-moth-whats-the-difference\">Butterfly vs moth: what&#8217;s the difference?<\/a><\/li><li><a href=\"https:\/\/www.discoverwildlife.com\/animal-facts\/insects-invertebrates\/whats-the-worlds-biggest-butterfly\">What\u2019s the world\u2019s biggest butterfly?<\/a><\/li><\/ul><p>The membrane itself has anti-glare properties thanks to a waxy coating.

After hatching from tiny spherical eggs in the\u00a0Sargasso sea, the first form is what is known as leptocephali. <\/p><p>These tiny, flattened (and also\u00a0transparent) larvae then develop into glass eels. This stage is much more recognisable as an eel than the previous one, with glass eels now having the distinctive serpentine body of the adult form, only on a much smaller scale (around 3-6 centimetres). T<\/p><p>hey are almost completely see-through, with their bones and organs visible beneath the skin. Unfortunately,\u00a0this life stage is considered a particular delicacy by some people, and there is a vast illegal trade in glass eels for human consumption. Overfishing of glass eels is one of the major threats to the European eel, a species that is classified as critically endangered.\u00a0<\/p><p><strong>More weird and wonderful wildlife<\/strong><\/p><ul><li><a href=\"https:\/\/www.discoverwildlife.com\/animal-facts\/birds\/weirdest-birds\">Weirdest birds: meet 12 strange and weird wonders of the avian world<\/a><\/li><li><a href=\"https:\/\/www.discoverwildlife.com\/animal-facts\/marine-animals\/weirdest-sea-creatures\">Weirdest sea creatures &#8211; meet 13 strange sea creatures of the deep<\/a><\/li><li><a href=\"https:\/\/www.discoverwildlife.com\/plant-facts\/fungi\/weird-fungi\">The weirdest fungi in the world, from dead man&#8217;s fingers to &#8216;zombie fungi&#8217;<\/a><\/li><li><a href=\"https:\/\/www.discoverwildlife.com\/plant-facts\/trees\/weirdest-trees\">Weirdest trees in the world: Discover nature&#8217;s wackiest tree wonders<\/a><\/li><\/ul> <\/body><\/html>\n<hr class=\"no-tts wp-block-separator\"\/>","protected":false},"excerpt":{"rendered":"<p>Nature&#8217;s invisible act: here are 10 transparent animals who have mastered the art of transparency with their very own invisibility cloak <\/p>\n","protected":false},"author":24,"featured_media":39015,"template":"","categories":[1],"acf":{"readingTimeMinutes":"8"},"uagb_featured_image_src":{"full":["https:\/\/c01.purpledshub.com\/uploads\/sites\/44\/2024\/06\/transparent-animals-discover-10-weird-invisible-creatures-you-can-see-right-though.jpg",2121,1414,false],"thumbnail":["https:\/\/c01.purpledshub.com\/uploads\/sites\/44\/2024\/06\/transparent-animals-discover-10-weird-invisible-creatures-you-can-see-right-though-150x150.jpg",150,150,true],"medium":["https:\/\/c01.purpledshub.com\/uploads\/sites\/44\/2024\/06\/transparent-animals-discover-10-weird-invisible-creatures-you-can-see-right-though-300x200.jpg",300,200,true],"medium_large":["https:\/\/c01.purpledshub.com\/uploads\/sites\/44\/2024\/06\/transparent-animals-discover-10-weird-invisible-creatures-you-can-see-right-though-768x512.jpg",768,512,true],"large":["https:\/\/c01.purpledshub.com\/uploads\/sites\/44\/2024\/06\/transparent-animals-discover-10-weird-invisible-creatures-you-can-see-right-though-1024x683.jpg",800,534,true],"1536x1536":["https:\/\/c01.purpledshub.com\/uploads\/sites\/44\/2024\/06\/transparent-animals-discover-10-weird-invisible-creatures-you-can-see-right-though-1536x1024.jpg",1536,1024,true],"2048x2048":["https:\/\/c01.purpledshub.com\/uploads\/sites\/44\/2024\/06\/transparent-animals-discover-10-weird-invisible-creatures-you-can-see-right-though-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":"Nature's invisible act: here are 10 transparent animals who have mastered the art of transparency with their very own invisibility cloak","_links":{"self":[{"href":"https:\/\/c01.purpledshub.com\/bbcwildlife\/wp-json\/wp\/v2\/rss_feed\/39014"}],"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\/39015"}],"wp:attachment":[{"href":"https:\/\/c01.purpledshub.com\/bbcwildlife\/wp-json\/wp\/v2\/media?parent=39014"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcwildlife\/wp-json\/wp\/v2\/categories?post=39014"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
