While it feed on a variety of crustaceans and bivalves, this species appears to be unique among cottids
in ingesting large numbers of snails (Norton 1988).

Uniformity between larval Icelinus and other cottid
larvae is noted in the assignment of phenetic groups based on shared larval characters (e.g., preopercular spine pattern, body shape, and pigmentation) (Richardson, 1981).

fishes of the Baltic Sea are bottomd-wellers.
genus Triglops Reinhardt (1830), including Prionistius Bean (1884), Elanura Gilbert (1896), and Sternias Jordan and Evermann (1898) as junior synonyms, contains 19 nominal species and subspecies, of which nine are currently recognized as valid (Pietsch, 1993).
Sea stars, glycerid polychaetes, and freshwater cottid
fish may detect prey by vibrational cues (Doering, 1982; Ockelmann and Vahl, 1970; Janssen, 1990).
The sites, Two-Mile Run (39[degrees]67'85", -79[degrees]05'87"), Mill Run (39[degrees]71'98", -79[degrees]29'81"), Casselman River (39[degrees]59'85", -79[degrees]20'71"), and Little Bear Creek (39[degrees]65'60", -79[degrees]26'11") were selected based upon the following criteria: (1) mottled sculpin as the only cottid
species present, (2) sculpin populations greater than 60 sculpin per 100 m of stream in order for the population to be considered large enough for removal offish samples, and (3) the appropriate level of embeddedness (15% or 35%) as measured by the Maryland Biological Stream Survey (2005).

This mode of reproduction was first described in the cottid
Alcichthys alcicornis (Elkhorn Sculpin), and is characterized by the association of eggs and spermatozoa in the ovary (Munehara and others 1989).
