Icedart

Icedarts are small aerial creatures native to the sub-arctic tundra of planet Darwin IV. Like many organisms on the planet, these lighter-than-air beings use a gas-filled bladder to stay aloft, though they also sport a pair of long wings, likely to enable them to achieve greater speeds. They also have three hollow spikes: one on the frontal part of their body, one on the posterior part and one on the ventral part. These spikes are used to absorb microscopic algae and other nutrients from the ice and snow, and also to cling to the ice in order to avoid being carried by snowstorms.
