Lithodes aoteoroa is a species of king crab in the family, Lithodidae, [1] and was first described in 2010 by Shane T. Ahyong. [1] [2]
Hermit crabs are anomuran decapod crustaceans of the superfamily Paguroidea that have adapted to occupy empty scavenged mollusc shells to protect their fragile exoskeletons. There are over 800 species of hermit crab, most of which possess an asymmetric abdomen concealed by a snug-fitting shell. Hermit crabs' soft (non-calcified) abdominal exoskeleton means they must occupy shelter produced by other organisms or risk being defenseless.
King crabs are a taxon of decapod crustaceans chiefly found in cold seas. Because of their large size and the taste of their meat, many species are widely caught and sold as food, the most common being the red king crab.
Squat lobsters are dorsoventrally flattened crustaceans with long tails held curled beneath the cephalothorax. They are found in the two superfamilies Galatheoidea and Chirostyloidea, which form part of the decapod infraorder Anomura, alongside groups including the hermit crabs and mole crabs. They are distributed worldwide in the oceans, and occur from near the surface to deep sea hydrothermal vents, with one species occupying caves above sea level. More than 900 species have been described, in around 60 genera. Some species form dense aggregations, either on the sea floor or in the water column, and a small number are commercially fished.
Anomura is a group of decapod crustaceans, including hermit crabs and others. Although the names of many anomurans include the word crab, all true crabs are in the sister group to the Anomura, the Brachyura.
Lithodes maja, the Norway king crab or trollkrabbe, is a species of king crab which occurs in colder North Atlantic waters off Europe and North America. It is found along the entire coast of Norway, including Svalbard, ranging south into the North Sea and Kattegat, the northern half of the British Isles, and around the Faroe Islands, Iceland, and off south-eastern Greenland. In the West Atlantic, it ranges from the Davis Strait between Greenland and Canada south to The Carolinas in the United States.
Lithodes santolla, also known as the southern king crab, king crab or centolla, is a species of king crab, found off southern South America including the Falklands/Malvinas. On the Pacific side, it is found in Chile from Valdivia at around 40° S to Cape Horn at 60° S. On the Atlantic side, it is found off Argentina. It lives in the benthic zone at depths of 0–700 m (0–2,300 ft). In Chile, it mostly lives at depths to 150 m (490 ft), but south of 40° S it has been found at 600 m (2,000 ft). It is a large crab that can reach up to 19 cm (7.5 in) in carapace length.
Lithodes is a genus of king crabs. Today there are about 30 recognized species, but others formerly included in this genus have been moved to Neolithodes and Paralomis. They are found in oceans around the world, ranging from shallow to deep waters, but mostly at depths of 100–1,000 m (300–3,300 ft). They are restricted to relatively cold waters, meaning that they only occur at high depths at low latitudes, but some species also shallower at high latitudes. They are medium to large crabs and some species are or were targeted by fisheries.
Neolithodes is a genus of king crabs, in the family Lithodidae. They are found in all major oceans, both in high and low latitudes. Although there are records from water as shallow as 124 m (407 ft) in cold regions, most records are much deeper, typically 700–2,000 m (2,300–6,600 ft), with the deepest confirmed at 5,238 m (17,185 ft). They are fairly large to large crabs that typically are reddish in color and spiny, although the size of these spines varies depending on species.
Paralomis zealandica, also known as the prickly king crab, is a species of king crab which lives at a depth of 254–1,212 m (833–3,976 ft) in New Zealand. It has spiky carapace. The scientific name of the species was first validly published in 1971 by Dawson & Yaldwyn. P. zealandica can be distinguished from other species in New Zealand waters by its thick covering of strong upright spines all over, including on its abdomen and along its legs and claws. The rostrum has three short, strong and sharp spines. It is the most prominent species of Paralomis in New Zealand.
Eurynolambrus australis, commonly known as the triangle crab, and by its Māori name riangi, is a small species of crab that is widespread throughout New Zealand.
Neolithodes flindersi is a species of king crab found in southeastern Australia. They have been found at depths of 887–1,333 metres (2,910–4,373 ft) but typically appear from 950–1,050 metres (3,120–3,440 ft). They most closely resemble Neolithodes brodiei and Neolithodes nipponensis.
Neolithodes yaldwyni is a species of king crab which is found in the Ross Sea from depths of 124–1,950 metres (407–6,398 ft). It had previously been misidentified as Neolithodes brodiei, and it closely resembles Neolithodes capensis.
Neolithodes bronwynae, commonly known as the rock crab, is a species of king crab which is found at the Whakatane Seamount in the Bay of Plenty, the Lord Howe Rise near Lord Howe Island, and possibly New Caledonia. It lives at a depth of 1,515–1,920 metres (4,970–6,299 ft). It has long spines and a deep-red colour.
Neolithodes brodiei is a species of king crab which is native to New Zealand and its adjacent waters. It lives at a depth of 500–1,240 metres (1,640–4,070 ft) but is typically found within a depth of 950–1,150 metres (3,120–3,770 ft). It has a deep-red colour, and its carapace has many small spinules along with larger spines. It is classified as "Not Threatened" by the New Zealand Department of Conservation.
Neolithodes capensis is a species of king crab which is found in the Southern Ocean and the western Indian Ocean. It has been found to a depth of 660–3,200 metres (2,170–10,500 ft).
Neolithodes diomedeae is a species of king crab which is found in the eastern Pacific Ocean, the southwestern Atlantic Ocean, and the Bellingshausen and Scotia Seas in the Southern Ocean.
Neolithodes nipponensis is a species of king crab which is found in Japan and Taiwan. It has been found at depths from 200–1,752 metres (656–5,748 ft).
Neolithodes duhameli is a species of king crab which is found in the Crozet Islands in the southwestern Indian Ocean from a depth of 620–1,500 metres (2,030–4,920 ft).
Paralomis dawsoni is a species of king crab which lives in New Caledonia, New Zealand, and the Solomon Islands at depths of 400–1,118 m (1,312–3,668 ft). It is the largest species of Paralomis in New Zealand.
