Jasus is a genus of spiny lobsters which live in the oceans of the Southern Hemisphere.[2] They have two distinct "horns" projecting from the front of the carapace, but lack the stridulating organs present in almost all other genera of spiny lobsters.[2] Like all spiny lobsters, they lack claws, and have long stout antennae which are quite flexible.[2]

Fisheries
Most of the extant species are liable to commercial exploitation, with the majority of the A$4.6 million New South Wales lobster fishery industry being based on J. edwardsii and the closely related Sagmariasus verreauxi.[6] Jasus lalandii is the most important commercial rock lobster in southern Africa.[7]
