Distribution Artic south to Cape Cod and east of Long Island Sound but see Identification note. [details] Habitat Infralittoral of the Gulf of St Lawrence? and estuary but see Identification note. Littoral in Gulf of Maine, Bay of Fundy south to Cape Cod. [details] Identification In NW Atlantic, Lineus ruber and Lineus viridis are commonly confused, especially with larger, dark-colored specimens. Head is reddish in former, greenish (but with reddish brain) in latter. [details] SynonymyBorlasia gesserensis (partim) = Lineus ruber Gordius gesserensis (partim) = Lineus ruber Gordius minor (partim) = Lineus ruber Lineus gesserensis (partim) = Lineus ruber Lineus obscurus (partim) may be synonym to Lineus ruber , but there still is some uncertainty about the genusname of the first mentionned species [details]
