Global Range: Mainly in cooler offshore waters of North Atlantic and Baltic Sea; a report for the coast of Italy may be valid; more common in European waters than in American waters, where single strandings have been recorded for near Nantucket, Massachusetts, and in eastern Canada (Mead and Brownell, in Wilson and Reeder 1993). Range may be centered in the North Sea. See Bonde and O'Shea (1989) for information on a 1984 stranding in Florida (regarded as a stray). Poorly known; as of late 1980s, less than 40 published stranding records, 11 in North America (Bonde and O'Shea 1989; 1990, Can. Field-Nat. 104:414-420). See Lien and Barry (1990) for information on status in Canada. Hooker and Baird (1999) described recent observations of groups of individuals in the Gully, Nova Scotia.
