Skyshells are a genera of Hanging Jelly native to two continents including Kenerif, characterized by the hardened shells on the top of their bodies. While many are no larger than a balloon, some species make up colossal floating islands up to 20 meters across and can even support the weight of several adult Regalti. Some fall back to the ground or ocean and keep growing. The largest specimen ever found still lives near the Void Lagoon and measures nearly 300 meters across and has the appearance of an unusual hill.
Etymology and Classification
The scientific classification for all Collena lifeforms uses the similar Earth-based classification all the way to the family or genera level for quick familiarization. Skyshells are Medusozoa because they have distinct polyp and medusa stages of life, and are Scyphozoa because they are considered 'true jellyfish'. They are Discomedusa due to their similar bell structures. Cael Concha is Latin for 'Sky Shell'.
Of the two Vevari words to describe skyshells, both have Rock or 'Alm' in the word. Yoralmi translates to "Sky Rock", and Goralm translates to "Stinging Rock". The Fevarik Regalti are very familiar with several varieties of skyshell.
Sky Shells broke off from the Scyphozoa class around 200 million years ago like other hanging jellies from other classes of Medusozoa. Able to easily survive on land thanks to the extinction of arthropods, terrestrial jellyfish of the class Scyphozoa became lighter than air. Unlike the related class of Hydrozoa that stayed relatively close to the ground, Sky shells floated much higher in the sky, up to thousands of meters in the air.
Their hard shells are an adaptation against the talons of flying animals from the time, back when early birds still flew and flying reptiles were everywhere. In time as the sizes of these creatures grew ever larger, so did the size of their shells. They became large enough to support entire ecosystems and due to the hunting habits of Sky Shells, many unwittingly picked up flightless animals into the skies where they evolved into entirely different creatures not seen anywhere near the ground.
