Vertical distribution, morphology and diet of proboscidactyal stellata (Cnidaria: limnomedusae) in lough hyne marine nature reserve, co. cork, ireland

摘要

The vertical distribution, morphology and diet of Proboscidactyla stellata (Cnidaria: Limnomedusae) were studied in Lough Hyne over a two year period. Vertical hauls of four depth strata, 40-30 m, 30-20 m, 20-10 m and 10-0 m, were taken monthly and at 4 h intervals fro a period of 48 h in July and 24 h in September 1994. Proboscidactyla stellata was largely concentrated in the lower 20 m of the water column reaching a maximum of 21 m~-3 at 30-20 m depth in June 1993.
