The Diskflyer is a small, non-sapient flying creature native to the planet of Darwin IV. Their mouths are located on the underside of their disk-shaped bodies. They have been theorised to propel themselves through the air by combusting methane gas in jet pods, like other flying creatures of the planet, such as Skewers.

Diskflyers live in or around the Amoebic Sea region. Sometimes they land on the "sea" surface to rest and feed on the jelly-like substance that composes it. Although Diskflyers live and fly in large groups, they are territorial creatures: each group operates in a distinct, four kilometer square territory. It is unknown whether young Diskflyers remain in the territory in which they were born, or leave to find their own territory and possibly start their own group.
