Lithodes aotearoa is a large species of king crab endemic to New Zealand.[4] It had formerly been confused with L. longispina and L. murrayi, which until 2010 were thought to occur in the region.[5] It is the second most widespread and common lithodid in New Zealand waters after Neolithodes brodiei,[6] and the New Zealand Department of Conservation classifies it as "Not Threatened".[1]
Description
Lithodes aotearoa is deep-purplish red in colour and has a pyriform carapace.[7] The carapace is covered with prominent, slender spines in juveniles and short, conical spines in adults.[8] Inbetween the spines are a smooth surface sparsely dotted with granules or small secondary spines.[8] Its carapace has been measured as large as 195.0 mm (7.68 in) in postrostral length and 199.1 mm (7.84 in) in width in a male specimen.[9][a] The largest known female carapace measures 190.5 mm (7.50 in) in postrostral length and 183.9 mm (7.24 in) in width.[10][a] Its rearmost pair of walking legs is the longest, and its legspan can be over 130 cm (51 in).[11] It is the largest lithodid known from New Zealand.[9]
Commercial fishing
Lithodes aotearoa are commercially fished in the waters around New Zealand.[12] They are included, with Neolithodes brodiei, in the total allowable commercial catch of up to 90 t (200,000 lb; 99 short tons) for king crabs under New Zealand's Quota Management System.[12]
