The modifications are constant in a given species, so that the fifth feet in this genus furnish the most important means of specific identification

RMRE0CCJ–. The life of inland waters; an elementary text book of fresh-water biology for American students. Freshwater biology. Copepods 189 The species of Diaptomus are remarkable for having usually very long antennas and often a very lively red color. Sometimes they tinge the water with red, when present in large numbers. Copepods feed upon animals plancton and algae, especially diatoms. They are themselves important food for fishes, especially for young fishes. The higher Crustacea, (Malacostraca) are rep- resented in ovir fresh waters by four distinct groups, all of which agree in having the body c

RMRDAEGJ–. Fresh-water biology. Freshwater biology. 744 FEESH-WATER BIOLOGY The fifth feet in Cyclops are very rudimentary structures. In Diaptomus the fifth feet take on interesting forms. In the female they are symmetrical, but not so well developed as the preceding swimming feet. But in the male, the right fifth foot differs from the left, and is modified so as to make a grasping organ. The figures in the synoptical key show the form of these appendages. The modifications are constant in a given species, so that the fifth feet in this genus furnish the most important means of specific identification
