284 A NATURALIST IN THE GREAT LAKES REGION 



(Fig. 431) are also inhabitants of the smaller brooks, while the 



golden shiner, the common sucker (Fig. 432), and the chub sucker 



(Fig. 192) also get well up stream. 



The following may be considered primarily creek fish: the 



black bullhead, red horse, stone roller (Fig. 433), common shiner, 



river chub, common 

 top minnow, Fundu- 

 lus dispar (Fig. 434), 

 fantailed darter (Fig. 

 440). While those 

 that are found in the 

 rivers are the mud cat, 

 the stone cat, banded 

 darter, hog-nosed 

 sucker (Fig. 435), 



FIG. 434. Top minnow, Fundulus dispar, male 

 and female. 



straw-colored min- 



now (Fig. 436),redfin, 

 red-faced minnow, gizzard shad, mud minnow, brook silver- 

 sides, rock bass (Fig. 437), 

 small-mouthed black bass, 

 black and white crappies (Fig. 

 438), the last four especially 

 in the gravel-bottomed pools. 

 In the estuary are to be 

 found those fish that are 

 ordinarily lake-inhabiting 

 forms such as the dogfish, tad- 

 pole cat, buffalo, grass pike, 

 bluegill, pumpkin-seed, large- 

 mouthed black bass, pike 



perch, and yellow perch. This is, of course, not to be inter- 

 preted as meaning that the brook fish, the creek fish, or the 

 others are confined to one particular habitat, but merely that 

 if one makes systematic collections they will be captured most 

 frequently in the situations indicated.
