Jasus edwardsii (Hutton, 1875) |
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
All seven species are liable to commercial exploitation, with the majority of the AUS$ 4.6 million New South Wales lobster fishery industry being based on J. verreauxi and J. edwardsii .[3] J. verreauxi and J. edwardsii are the only "lobsters" to occur around the coasts of New Zealand .[4] Jasus lalandii is the most important commercial rock lobster in southern Africa .[5]
