The mechanosensory system of the lateral line in the Scorpaeniformes order, has been studied in taxa like Liparidae (Chernova & Stein, 2004; Lanoo et al., 2009), Cottidae
(Jones & Jansen, 1992; Telcean et al., 2005; Coombs & Grossman, 2006), Hexagrammidae (Wonsettler & Webb, 1997) and Normanichthyidae (Mandrytsa, 1993).
In the Scorpaeniformes, one species in Sebastidae, Sebastesfasciatus, exhibited Hb polymerization, while four species in three other families, Cottunculus microps family Psychrolutidae, Myoxocephalus octodecemspinosus family Cottidae
, Myoxocephalus scorpius family Cottidae
, and Hemitripterus americanus family Hemitripteridae, did not exhibit the trait (Tables 1, 2).
Similar reproductive characteristics have been observed in other teleost fishes of the families Clupeidae, Cyprinidae, Salmonidae, Percidae, Scorpaenidae, and Cottidae
(Munoz et al., 2002; Petersen et al., 2004; TenBrink and Aydin (3); McBride et al., 2015).
Molecular systematics of the genus Cottus (Scorpaeniformes: Cottidae
The intromittent organs of the fluffy sculpin (Oligocottus snyderi; Family Cottidae
), a viviparous marine species, have been described as having a modified anal fin ray with the ability to bend in order to enter the female reproductive tract (Morris 1955).
(2010a, 2010b) investigated the ossicles of the Cottidae
, Cyclopteridae and Liparidae (Scorpaeniformes) and SEM imaged the taxonomically important tooth plates and gill raker tubercles of these fishes.

The scales and their modifications in pleuronectiforms are easily distinguished from comparable ossicles in teleosts we studied earlier (Cottidae
, Cyclopteridae, Liparidae, Gasterosteidae, Syngnathidae), though there are interesting comparisons between the spined and lateralline scales as well as tubercles of pleuronectiforms and cottiforms (cf.
This includes species observed in the spring diet, such as eulachon, Thaleichthys pacificus, and sculpin, Cottidae
; cod, Gadidae; and flatfish, Pleuronectidae (Quakenbush et al., 2015).
Smaller individuals (< 40 mm length) that could not be identified to species in the field were identified to family (e.g., Cottidae
