Utricularia [SEP] Introduction
The traps can range in size from 0.2 mm to 1.2 cm. Aquatic species, such as "U. vulgaris" (common bladderwort), possess bladders that are usually larger and can feed on more substantial prey such as water fleas "(Daphnia)", nematodes and even fish fry, mosquito larvae and young tadpoles. Despite their small size, the traps are extremely sophisticated. In the active traps of the aquatic species, prey brush against trigger hairs connected to the trapdoor. The bladder, when "set", is under negative pressure in relation to its environment so that when the trapdoor is mechanically triggered, the prey, along with the water surrounding it, is sucked into the bladder.
