    • n swimmeret In Crustacea, a swimming-foot; a pleopod; an abdominal limb or appendage usually adapted for swimming, and thus distinguished from the ambulatory or chelate thoracic limbs, fitted for walking or seizing. In the lobster there are five pairs of swimmerets, each consisting of a developed endopodite and exopodite, the last pair, more highly modified than the rest, forming with a median piece or telson the large flaps or tail. (See rhipidura.) Swimmerets are also used for other purposes, as the carrying of the spawn, coral, or berry of the female.
