Certain of them like- the pike (fig. 28) are specialized for feeding at the surface: others, like the sucker (fig. 29), for feeding at the bottom, and the mcflith is turned up or down accordingly. The best of them are carnivorous and eat habitually other smaller fishes. The rock bass seems to prefer crawfishes as food. Most of them eat the larvae of mayflies and midges, though the pikes demand bigger game. The sheepshead eats mol- luscs, crushing the shells with its flat-topped molar-like teeth. Fishes are among the most beautiful of living things. Their colors are splendid. Their motions are all easy and graceful. Their habits are most interesting and varied. Nearly all the common forms are included in six or seven families: the cat fishes, the trouts, the pikes (including the pickerel), the suckers, the minnows (including the huge carp), the perches and the sunfishes (including the basses). It is the purpose of the following study to promote acquaintance with some of these. Study 5. Creek Fishes A representative lot of a dozen or more of the larger com- mon fishes should be available for this exercise. It were better to have most of them collected in advance and kept alive for examination. A seine may be drawn, or traps taken up, as a part of the exercise, but often there are uncertainties.
