Ecology Summary - Galeorhinus galeus

Language:

Main Ref.	Ripley, E., 1946
Remarks	Occurs on the continental shelf and slope (Ref. 75154). Demersal piscivore (Ref. 12223). In the southern waters of Australia, school sharks are found in schools which are of mainly similar sex and similar size. A great part of the population migrates to the warmer waters of South Australia and New South Wales in the late summer and winter months. They return to the Bass Strait and the continental shelf around Australia during October or November (Ref. 6390). The species undertakes long migrations (movements) up to 2,500 km in the northeast Atlantic and to 1,400 km in southern Australia (Ref. 6871).
