"Disk-ants are small, but they might be the deadliest life we found on the island, Their backs are covered with spirals of babies whose backs are covered with spirals of babies, and so on, down to the size of nano-ants, or ‘nants,’ as we call them. They roll on their edge, moving much faster than normal ants, and when they strike, the nants unload from their backs and melt flesh right off their prey’s bones. They can crawl on either side, as well, and hurl themselves through the air like Frisbees.” - Andy, Pandemoniuum.
Disc Ants (Rotaformica Hendersi) are small omnivores native to Henders Island. Despite the name they are not tree ants but are very distant relatives, categorised as a differing subphylum of the Athropod phylum. They are among the few animals to have evolved the ability to move by rolling, but are also capible of walking and throwing themselves through the air at their targets.
Discs ants are penta-symmetrical. They resemble small disks divided into five segments with a two pairs of retractable limbs protruding from each segment. They have a mouth at their bottom-center and have an armoured top with a spiral pattern. Disc Ants have eyes on their sides allowing them to see as they roll.
Disc Ants are colonial organisms. Each adult Disc Ant contains a colony of juvenile ants inside them. These juveniles carry young of their own all the way down to microsopicc size called nants (nanite ants). They function as a super organism attacking in unison devouring their prey. Small ants are repelled by symbiants living on larger organisms on Henders Islands. Both juvenile Disc-Ants and Symbiants will turn on their host if it is dying.
Disc Ants are capible of budding into coral like 'plants' in the right ecological circumstances. These plants include the Dart Palm, Snap Blossum and Tube Trap.
