摘要：

D. sculpta was collected from shallow water (1-15 m) in Passamaquoddy Bay [Canada] over a 26 mo. period. D. sculpta produces a rapidly growing and developing summer generation between 2 successive winter generations. The overwintering generation releases young in mid-July and late Aug. The summer generation releases young in Nov. The mean fecundity of the summer-gravid females (78.4) is much greater than the mean fecundity (20.0) of the fall-gravid females. The maximum life-span is 5 mo. and 12 mo. for members of the summer and winter generations, respectively.
