Jasus

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]

Species[edit]

The following species are included in the genus Jasus:[3]

Another species, formerly known as "Jasus verreauxi" is found around New Zealand (especially the North Island), the Chatham Islands, and around Australia (Queensland to Victoria and Tasmania); it is now placed in the genus Sagmariasus.

Approximate distributions of the extant species of Jasus, after Phillips (2006).[5]
Orange: J. caveorum; pink: J. frontalis; red: J. tristani; yellow: J. lalandii; blue: J. paulensis; green: J. edwardsii

Fisheries[edit]

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]
