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.

For seine and trawl catches, unidentified small flatfish (Pleuronectidae), gadids (Gadidae), pricklebacks (Stichaeidae), and sculpins (Cottidae) were counted in the total catch, but were not considered separate species for species richness calculations because at least one identifiable species from these taxa was captured; unidentified small snailfish and unidentified small poacher were considered separate species because no identifiable species from the families Liparidae
and Agonidae were captured.
It is likely that members of the families Zoarcidae and Liparidae
also exhibit parental care, but this has not been confirmed.
