It allows animals to sense electric fields generated by other living organisms or environmental factors.<\/li>\n<li>This ability is primarily found in certain <strong>vertebrate species<\/strong>, especially <strong>aquatic animals<\/strong> like <strong>sharks<\/strong> and <strong>electric fish<\/strong>, but is now also observed in <strong>invertebrates<\/strong> like <strong>fruit fly larvae<\/strong>.<\/li>\n<li><strong>Electroreceptor organs<\/strong> were first discovered in the <strong>1960s<\/strong> through physiological studies of <strong>weakly electric fish<\/strong> by <strong>Theodore H. Bullock<\/strong>, an American neuroscientist, and French scientists <strong>Thomas Szabo<\/strong> and <strong>Alfred Fessard<\/strong>.<\/li>\n<li>In some species, <strong>electroreception<\/strong> is also used for <strong>social communication<\/strong>, indicating its evolutionary importance beyond navigation or hunting.<\/li>\n<\/ul>\n<h2>Key Findings<\/h2>\n<ul>\n<li>The researchers found that <strong>only a small cluster of sensory neurons<\/strong> located on <strong>either side of the larva\u2019s head<\/strong> were involved in this electroreceptive behavior.<\/li>\n<li>Upon closer analysis under a microscope, it was confirmed that <strong>a single neuron<\/strong> in this head cluster was <strong>directly responsible<\/strong> for detecting the electric field.<\/li>\n<li>The neuron exhibited <strong>directional sensitivity<\/strong>\u2014it was <strong>inhibited<\/strong> when the negative electrode was in front of the larva\u2019s head and <strong>activated<\/strong> when the electrode was behind, which triggered the larva to <strong>reorient and move<\/strong> accordingly.<\/li>\n<li>By <strong>eliminating other possible stimuli<\/strong> (confounding factors), the scientists confirmed that the larval response was specifically due to <strong>the electric field itself<\/strong>, not other environmental cues.<\/li>\n<li>This makes <strong>fruit fly larvae<\/strong> one of the few organisms, along with <strong>sharks<\/strong>, <strong>bees<\/strong>, and the <strong>platypus<\/strong>, known to exhibit this rare sensory ability.<\/li>\n<li>In controlled experiments, <strong>larvae immersed in an electric field<\/strong> were observed to <strong>reorient their movement<\/strong> and navigate <strong>towards the negative electrode<\/strong>, indicating that they could detect and respond to the direction and strength of the electric field.<\/li>\n<\/ul>\n<h2>Electroreception FAQs<\/h2>\n<p><strong>Q1. <\/strong>What is electroreception?<br \/>\n<strong>Ans.<\/strong> A sensory ability in some aquatic animals (e.g., sharks, platypus) to detect electric fields, aiding navigation, hunting, and communication.<\/p>\n<p><strong>Q2. <\/strong>How do sharks use electroreception?<br \/>\n<strong>Ans.<\/strong> Via ampullae of Lorenzini\u2014gel-filled pores detecting prey\u2019s muscle contractions, even in murky waters.<\/p>\n<p><strong>Q3. <\/strong>Are electroreceptive species found in India?<br \/>\n<strong>Ans.<\/strong> Yes! Gangetic dolphins use electroreception to navigate silt-laden rivers, while electric rays inhabit coastal waters.<\/p>\n<p><strong>Source: <\/strong><a href=\"https:\/\/www.thehindu.com\/sci-tech\/can-fruit-fly-larvae-sense-electric-fields\/article69439949.ece\" target=\"_blank\" rel=\"nofollow noopener\">TH<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Electroreception is the ability to detect weak electric fields, helping animals sense other organisms or environmental changes through bioelectric signals.<\/p>\n","protected":false},"author":5,"featured_media":32018,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[],"class_list":{"0":"post-32017","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-upsc-prelims-current-affairs","8":"no-featured-image-padding"},"acf":[],"_links":{"self":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/32017","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/comments?post=32017"}],"version-history":[{"count":0,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/32017\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media\/32018"}],"wp:attachment":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media?parent=32017"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/categories?post=32017"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/tags?post=32017"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
