Mottled sculpin

The mottled sculpin (Cottus bairdii) is a freshwater sculpin (family Cottidae) found widely although unevenly throughout North America. As the name suggests, its coloration is a combination of bars, spots, and speckles randomly distributed. The large pectoral fins are banded. The first dorsal fin is made of slender and somewhat soft spines, and just barely joins with the second dorsal. Maximum length is 15 cm.
