Bubble Breath

See that bubble at the rear end of this aquatic beetle? That is this beetle's little stash of air to breath while he hunts for underwater critters to eat or hides from my camera underneath this blade of grass.

Beetles go up to the surface rear first to obtain a new bubble of air that can keep them oxygenated for several minutes under water; no air tank needed here.
