The shallow-water treeworm split from the joint-winged treeworm to inhabit the Irinya River and Irinya Swamp. There the treeworm adapted to living near shallow waters. It grows in riverbanks and shallow waters of the swamps. It is much smaller than its massive ancestor and has shorter arm-leafs. Each wing-leaf is also split into many finger-branches. Like its ancestor its wings are anchored in the soil, but instead of joints the arms grow a triangular split part of the branch into the ground. Like its ancestor it has an advanced root system, usually eight sub-roots. It uses the xenobee that moved into the swamps and river after inhabited them for pollination.
Its legless larvae now found a new solution for locomotion and transportation. As they hatch they jump into the water and paddle their way using their wing-leafs until they find a shore or land-spot that isn’t claimed and root themselves in it.
