Certain fishes depend on minute forms of plants and ani- mals, and therefore some means is needed by which the water taken in with the food may be gotten rid of while at the same time the food is retained. Hence, fishes are provided with a straining apparatus which permits the water to escape when the mouth is closed, and retains within the mouth the minute forms of life that it has secured. Of this adapta- tion for food getting, we shall learn more in our study of the gills. Most of the fishes that prey on other animals secure their victims by dint of their speed; but one form of fish, called. > â msi^i:^ J Fia. 97. â Deep sea angler. .the "deep sea angler" (Fig. 97), has upon the dorsal part of the head a bulbous projection, the tip end of which is limii- nous.
