TROPICAL AQUAKIUM FISHES 177 UTRICULARIA Many species of Uladderwort are distributed throughout the Temper-ate Zone. They have somewhat the appearance of the finely-dividedleaves of Myriophyllum, but may be identified by the small bladders(lotted throughout. Our figure 125 of U. vulgaris gives a good idea ofthe general type. They thrive in the aquarium if given plenty of stronglight. The Bladderworts are carnivorous plants, trapping the micro-scopic lower forms of animal life in their bladders, where they are di-gested.
