This branch from the stilt plent has highly shortened forelegs, meaning its head is almost at the ground. Its breathing hole has moved to the very highest part of its body, allowing it to wade through the swamps sucking up mud. The mud is passed through a filter-like membrane in its mouth, and the water and fine particles are expelled from holes where the tympanic membranes once were. It also possesses a rudimentary mouth-plate, which allows it to chew up the roots of any plants it may come across. Its eyes have become very small due to the murky conditions in which it lives. However, they are still good enough to identify a basking plesiodile.
Due to the fact its head is almost constantly submerged, the adult plent has developed a special pouch in which to keep young. A tract leads from its stomach and breathing hole to its pouch, allowing the young to feed and grow until they are old enough to be spat out onto the shore and fend for themselves. The young amble around on land, eating young worms and plant shoots, until their back legs grow long and they move into the swamps, assuming the habits of their parents.
