A common inhabitant of swamps and wetlands, this carnivorous plant is inconspicuous and thus often overlooked.  The underwater stems are leaf-like and highly divided, and flowers that grow above water are yellow, two-lipped with a forward facing spur on the lower lip.  The bladders of bladderwort are used to capture various aquatic organisms.  The hair at the bladder's opening triggers the trap to open when contacted, drawing in water and the organism like a vacuum.  Then, bacteria and enzymes inside the trap aid in digestion.
