Lesser water boatman ( Micronecta scholtzi): The loudest penis on Earth
The lesser water boatman, just 2 millimetres long, is the loudest animal on Earth and more impressive fact is that he makes its noises using its penis instead of its mouth or legs or wings.
James Windmill, engineering expert, in mid-2011 from the Centre for Ultrasonic Engineering at the University of Strathclyde (Scotland) reported in PLoS One that the lesser water boatman can produce sounds at a level of 99.2 decibels. It produce by a process known as stridulation, which mean two body parts rubbing together to create a voice that can travel over large distances. The water boatman, rubs its penis against its abdomen for trying to invite females.
Windmill and his colleagues collected lesser water boatmen from a river and put them in water tanks fitted with hydrophones – microphones that record sounds underwater. The researchers place five in every tank because water boatmen are just active in groups and then recorded their voices. On average, the songs reached 78.9 decibels. According to Windmill, 99 per cent of sound is lost as it is transferred from water to air that’s why most of the sound doesn’t make it to human ears. Lesser water boatmen …show more content…
In 2011, scientists from France and England published in Nature that they had revealed a cluster of genes having single chromosome i.e. 30 genes in Numata butterflies that is responsible for this character and these genes are called supergenes that direct the different elements of wing patterns. Ecologist Mathieu Joron from France’s Muséum National d’Histoire Naturelle, recommended that each of these wing patterns have confirmed so successful in warning the birds and other pray. Another option is that the butterflies could belong to unlike habitats that in which some patterns are more beneficial than
