light with black tips, pectoral fins mostly brown-black, but distal half of unbranched rays white.
Pectoral-fin posterior tip reaching from the origin of the pelvic fin
to the 4th anal-fin ray in males, from the origin of the pelvic fin
to the urogenital papilla in females.
TEHRAN (FNA)- The discovery of well-preserved pelves and a partial pelvic fin
from Tiktlik roseae, a 375 million-year-old transitional species between fish and the first legged animals, reveals that the evolution of hind legs actually began as enhanced hind fins.

carolinae have recently been described from Perry County, Missouri, that differ from epigean populations in relative eye size, amount of pigmentation, body shape, reduction in pelvic fin
ray number, and enlargement of cephalic lateralis pores (Burr et al.
Cottus carolinae collected from caves and resurgence streams in Perry County exhibit reduced pi gmentation and pelvic fin
ray counts compared to other surface streams in Missouri and to the literature.
Nearly full complements of fin spines and rays were present as early as the posttransition juvenile stage: the pelvic fin
had 1 spine and 4 rays; the pectoral fin had 17 rays; the dorsal fin had 12 spines and 16 rays; and the anal fin had 2 spines and 9 rays (Table 2; Fig.
Pectoral fins elliptical, posterior margin reaching urogenital papilla in males, reaching pelvic fin
base in females.
