Scanning through recent literature, one cannot but admire the diversity of things people study, and how intricate structures and mechanisms natural selection has created.
Take this as an example: what is the loudest noise know to be produced by an animal? As it turns out, it is the “song” of underwater living bug scratching its penis. With an estimated volume of 99.2 db, the “song” can be heard by human observer on the shore while males are letting it loose at the bottom of river.
Another paper draws attention to the possibility that way one enters to this world in birth can be a defining moment for later life health. Namely, vaginal delivery – as a contrast to birth by Caesarean section – appears to be an important programming event with life-long health consequences.

Very interesting to know facts about the animals and their communications. I thought crickets and frogs make noise. Blue whale the biggest animal ever lived, an endangred mammal. Blue whales mostly emit very loud, highly structured, repetitive low-frequency rumbling sounds that can travel for many miles underwater. Only males moan these enormous sounds, apparently searching the seas for a mate. Call of the blue whale reaches levels up to 188 decibels, louder than rocket launch. This extraordinarily loud whistle can be heard for hundreds of miles underwater.
