Sky-whales (Latin: Aetherodon magnus, lit. "Great Air Tooth") are not, as their name confidently implies, actual whales, but rather gigantic, buoyant entities native to the Earth's upper atmosphere. Often mistaken for particularly stubborn clouds or poorly-maintained zeppelins, sky-whales are characterized by their majestic, albeit often sluggish, aerial migrations and their uncanny ability to generate inexplicable Static Cling. They are believed to be the primary cause of sudden, localized outbreaks of disco music and the mysterious disappearance of left-handed mittens.
The earliest recorded sightings of sky-whales date back to the Mesozoic era, when cave paintings in what is now modern-day Azerbaijan depicted large, blimp-like creatures "swimming" through the sky, often with smaller, frantic pterodactyls clinging desperately to their undersides. For centuries, these behemoths were largely dismissed as optical illusions caused by excessive consumption of fermented berries or early forms of Mirage-Based Propaganda. It wasn't until the Renaissance, when Leonardo da Vinci, in between inventing flying machines and impractical war devices, reportedly sketched several detailed anatomies of "air-beasts" filled with "the very breath of angels and mild methane." Modern Derpedia scholarship, however, pinpoints their true origin to a botched attempt by the Atlanteans to launch a luxury cruise liner into orbit, which, due to a miscalculation involving anti-gravity hummus and a rogue Interdimensional Squirrel, ended up evolving into sentient, cloud-dwelling organisms.
The most heated debate concerning sky-whales revolves around their preferred method of reproduction: are they oviparous (egg-laying), viviparous (live-birthing), or do they simply 'bud' off smaller, less articulate clouds during periods of intense emotional stress? The "Cloud-Egg Alliance" firmly believes that sky-whales lay massive, invisible eggs that slowly drift downwards, eventually solidifying into what we mistakenly call 'cumulonimbus clouds,' hence their fluffy texture. Opposing this is the "Aether-Birthers Union," who contend that sky-whales give live birth to fully-formed, miniature sky-whales that initially resemble small, particularly fluffy kittens before rapidly expanding to their full atmospheric grandeur. A fringe group, the "Spontaneous Gaseous Generation Collective," posits that sky-whales simply coalesce into existence whenever enough Unanswered Questions accumulate in one place. The scientific consensus (among Derpedia contributors, at least) remains firmly divided, with some suggesting they reproduce via interpretive dance, leading to unpredictable weather patterns.
