This is the bladder trap of an aquatic bladderwort under a microscope. Believe it or not, this is a modified leaf! It creates a vacuum inside the tiny balloon shaped leaf. The long guide hairs help swimming creatures find their way to the mouth, which is darker in this photo. When something approaches the mouth opens and the sides of the bladder pop out sucking the unfortunate victim in at 1/5000 of a second! It’s one of the fastest most complicated things in nature and it is still not clearly understood!
Like tiny, vegetative anglerfish, predatory plants on a microscopic level give their creature counterparts a run for their money. –MN
