Paralomis dawsoni is a species of king crab which lives in New Caledonia, northern New Zealand, and the Solomon Islands at depths of 400–1,118 m (1,312–3,668 ft).[2][3][4] Alongside P. zealandica, it is one of the two most common species of Paralomis in New Zealand.[3] As of 2023, the Department of Conservation in New Zealand classifies P. dawsoni as "Naturally Uncommon".[1]

Appearance

[edit]

P. dawsoni is orange-red or red-brown in colour and has a subhexagonal carapace covered uniformly in blunt tubercles.[3] Tubercles and coarse spines cover its legs, and its chelipeds are especially spinose.[3] It is the largest species of Paralomis known to occur in New Zealand, with one specimen measured to have a post-pseudorostral carapace length of 142.7 mm (5.62 in) and a carapace width of 139.8 mm (5.50 in).[3]

Etymology

[edit]

The species name "dawsoni" is dedicated to Elliot Watson Dawson of the National Museum of New Zealand.[2]
