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
The following species are included in the genus Jasus:[3]
- Jasus caveorum Webber & Booth, 1995
- Jasus edwardsii (Hutton, 1875) – Southern Australia: Western Australia to New South Wales & Tasmania. South Island of New Zealand
- Jasus frontalis (H. Milne-Edwards, 1837) – Juan Fernández Islands, Islas Desventuradas
- Jasus jlemingi Glaessner, 1960 – a Miocene fossil from New Zealand [4]
- Jasus lalandii (H. Milne-Edwards, 1837) – Southern Africa (Namibia to Algoa Bay, South Africa
- Jasus paulensis (Heller, 1862) – St. Paul Island and Amsterdam Island
- Jasus tristani Holthuis, 1963 – Tristan da Cunha archipelago; Vema seamount
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.
Orange: J. caveorum; pink: J. frontalis; red: J. tristani; yellow: J. lalandii; blue: J. paulensis; green: J. edwardsii
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]
