DetailsAquatic sowbugs are not good swimmers. They do not have a tail to flip like a scud, but have a flat body with long legs made for clinging. When caught up in the current, an aquatic sowbug does not roll up in a ball like a roly-poly, but arches its back, positions itself straight up and down, and flails its long legs about wildly in an attempt to grab onto something. This is the posture Sow Chow imitates.
Sow bugs are not scuds, but they cross over as a pattern quite well!
