Its function is thought to be, perhaps surprisingly, to attract the opposite sex.\u00a0In order to call to females, the male emits as loud and deep a roar as he can.<\/p> <p>This advertises his health and dominance to prospective mates. Having such a long and flappy nose is thought to allow them to produce louder calls by acting as an echo chamber.\u00a0<\/p> <p>So\u00a0there you have it, a massive nose can make you sexier.\u00a0<\/p> <h3 class=\"wp-block-heading\">Aye aye\u2019s finger (<em>Daubentonia\u00a0madagascariensis<\/em>)<\/h3> <figure class=\"wp-block-image size-full\"> <img loading=\"lazy\" decoding=\"async\" width=\"4847\" height=\"3607\" src=\"https:\/\/c02.purpledshub.com\/uploads\/sites\/62\/2022\/11\/Aye-ayeMadagascarThorsten-NegroGettyImages-975197902-2d4335e.jpg\" alt=\"Aye-aye, Madagascar. \u00a9\u00a0Thorsten Negro\/Getty\" class=\"wp-image-70825\"\/> <figcaption class=\"wp-element-caption\"> Getty images <\/figcaption> <\/figure> <p>Another primate, but this time a <a href=\"https:\/\/www.discoverwildlife.com\/animal-facts\/mammals\/facts-about-lemurs\">lemur<\/a>, <a href=\"https:\/\/www.discoverwildlife.com\/animal-facts\/mammals\/aye-aye-facts\">aye ayes<\/a> are found in <a href=\"https:\/\/www.discoverwildlife.com\/holidays-days-out\/africa\/madagascar-wildlife\">Madagascar<\/a>.
