|[C16: from Old French graspois, from gras fat (from Latin crassus) + pois fish (from Latin piscis)]|
a common offshore inhabitant of tropical and temperate ocean waters, a member of the dolphin family (Delphinidae). The grampus measures about 4 metres (approximately 13 feet) in length and has a blunt head and a distinct longitudinal forehead crease. It is unique among dolphins in usually having no upper teeth and from zero to seven teeth in the lower jaw. Older males are heavily scarred about the head and trunk, apparently owing to encounters with other grampuses.
