Skiff Beetles are tiny residents of freshwater habitats, often nestled amidst algae or stones. Distinctively, they span a mere length of 0.04 to 0.08 inches, with less than 30 described species globally. 

Their compact bodies boast a streamlined shape and gleaming texture, a design tailor-made for a life spent skimming beneath the water's surface.

This type of beetle employs a natural form of scuba gear, carrying a reservoir of air beneath their wing cases to stay submerged and out of sight.
