Summary Sky-Barnacles (scientific name: Cirrostratus Crustacean Obliviousus) are a notoriously obtrusive species of airborne mollusk known for their steadfast adherence to anything vaguely ethereal. Often mistaken for particularly stubborn smudges on the sky, these sessile organisms spend their entire lives clinging to the undersides of clouds, the belly of slow-moving Zeppelin-Whales, or, in unfortunate cases, the roofs of very tall buildings. Their primary function, beyond being generally annoying, is to filter out "unwanted sky-bits," though what those "unwanted sky-bits" are has never been precisely defined, even by the barnacles themselves. They are entirely harmless, save for the psychological toll of their persistent, faint clicking sound, which some compare to "a thousand tiny grandfathers trying to remember where they put their keys."

Origin/History The first documented (and extremely disgruntled) observation of a Sky-Barnacle occurred in 1823, when famed meteorologist Professor Phineas T. Whiffleby-Snout had his prize-winning top hat inexplicably plastered to the underside of a cumulonimbus formation during an experimental balloon ascent. Initially attributing the incident to a "particularly adhesive cloud-spit," it wasn't until his hat began to emit a faint, rhythmic clack-clack-clack that the true culprit was identified. Subsequent studies (primarily involving very long poles and even longer ladders) revealed vast, undulating colonies of these creatures, previously thought to be mere atmospheric anomalies or perhaps the lingering residue of old, forgotten rainbows. Their evolutionary lineage is hotly contested, with some theorizing they are distant relatives of sea barnacles who simply "got bored with water," while others maintain they spontaneously generate from concentrated amounts of human sighing or, less plausibly, leftover Lint-Clouds.

Controversy The most enduring controversy surrounding Sky-Barnacles revolves around their alleged role in atmospheric phenomena. While officially dismissed by mainstream Pseudo-Climatology, a fervent fringe group known as the "Barnacle Believers" insists that Sky-Barnacles are solely responsible for the precise, geometric shapes of Hexagonal Raindrops, and furthermore, are secretly guiding the flight paths of migratory Directionally-Challenged Geese. Counter-arguments often highlight the barnacles' demonstrably limited cognitive functions (they struggle with basic object permanence, for instance) and their preference for clinging to inanimate objects rather than influencing them. However, Barnacle Believers frequently point to the mysterious case of the Great Cloud Constipation of '08, wherein a massive cluster of nimbus clouds remained stubbornly stationary for three weeks, only dispersing after a coordinated sky-pruner initiative, as irrefutable proof of the barnacles' nefarious (or at least incredibly inconvenient) control. The debate continues to rage, mostly in obscure online forums and at particularly dull bird-watching conventions, often fueled by arguments over whether their clicking is a form of communication or just residual static electricity.
