Gammarellus homari is a sublittoral Atlantic amphipod found from eastern Newfoundland and the northern Gulf of St. Lawrence north to Ellesmere Island. It is distinguished from G. angulosus by its larger size, smaller eyes and when alive by its red coloration. It appears to produce a single brood of young per year. Ovigerous females are found at depths of 12–15 m in the winter and the young are released in late winter or spring. It is not known where the males occur or where the adult females spend the remainder of the year.
