REP: The Yetipillars by Ramul on DeviantArt (original) (raw)

Though derived from makropneumonopteres, yetipillars belong to their own group. Reaching the size of a sheep, this flightless animals are the largest existing pneumonopteres and are exclusively found in the subpolar and polar regions of the north, where they inhabit the niches of larger land herbivores, omnivores and carnivores and some amphibic species. Yetipillars live mostly in small groups, the solitary species belong mostly to the smaller forms. They incubate the eggs and young in pockets formed by their wings. While the more primitive species feed their young with the same food they collect for themselves, most yetipillars can excrete a nutritious fluid from derived slime glands that usually keep their lungs clean. Both genders have these breeding pockets and usually the male takes the eggs and gives them to the female once the young have hatched. In solitary species that don't form pairs during breeding season, the male aids the female to position the eggs in her breeding pocket before leaving.

Icerunner: one of the smaller species that is mostly carnivorous and mostly hunts flying pneumonopteres.
False oarfoot: An aquatic animal that uses the waterproof wing pockets additionally as an air reserve. This small group is very similar to the unrelated true oarfoots from the Southern Continent.
Longlipped yetipillar: a middlesized, omnivorous species and one of the few animals on Red Earth that regularly uses tools.
Mole yetipillar: an animal with front legs evolved into digging tools that feeds mostly on frostspire roots.
Ribbonmouth: belonging into a group of smaller yetipillars that grow colorful extensions on their upper lip that resemble frostspire "flowers" to attract their unsuspecting prey in form of migrating micropneumonopteres that feed on frostspire excretions and distribute their eggs. This group hibernates during winter.
