The twohorn sculpin (Icelus bicornis) is an Arctic benthic fish species of the order Scorpaeniformes.
Description
The twohorn sculpin is typically 5–12 cm long and may reach 15 cm. It has a thin caudal peduncle, one sharp spine located in front of each eye and two spines behind, hence its common name. Like other sculpins, this species has two dorsal fins (the first is spiny while the second is soft-rayed), large pectoral fins and slender pelvics. The caudal fin is slightly rounded and has dark, vertical bars and a black spot at the base. The body is yellowish, with many dark blotches on the back and sides.

In Canada, this fish occurs as far north as the northern tip of Ellesmere Island. Elsewhere, it is distributed along Norwegian coasts up to Spitzbergen and the Barents Sea (as far north as 82 degrees), and west to Iceland and Greenland. It is typically found at depths between 40 and 180 metres on sand, mud or rocky substrates.
Size
This species reaches a length of 15.7 cm (6.2 in).

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
