Whenever possible, the number of myomeres, spines, and rays of dorsal, anal, caudal, pectoral, and pelvic fins were recorded.
These PVMs are spaced at approximately one per myomere and stop just beyond the pigment band at 75% SL.
Larvae of northern sculpin have 35-36 myomeres, pelvic fins with one spine and two rays, a bony preopercular shelf, four preopercular spines, 3-14 irregular postanal ventral melanophores, few, if any, melanophores ventrally on the gut, and in larger specimens, two rows of ctenoid scales directly beneath the dorsal fins extending onto the caudal peduncle.
During days 17-21, the optic capsule and eye lenses formed, the head and anterior body became thick and more defined, and the notochord, myomeres, and Kupffer's vesicle became visible (Table 1).
3, A and B) showed a distinct pattern of 12 to 23 small postanal melanophores serially arranged, about one per myomere, along the ventral midline.
Because of the difficulty in accurately counting myomeres in transforming clupeids (Hettler, 1984; Ditty et al.
Myomeres were difficult to count reliably at either end and thus vertebral counts (which include the urostyle) of stained larvae were taken instead.
Each melanophore is recorded for the myomere on which it occurs, n indicates the number of specimens examined at each size range.
Myomere width measurements taken from formalin preserved larvae were used in the shrinkage correction model.
They have also found that the flattened eel-like creatures had skeletal muscles called myomeres and a basic blood vessel system.
