Paralomis okitoriensis is a species of king crab. [1] It has been identified near Japan's southernmost atoll, Okinotorishima. [1]
P. okitoriensis is orange-red in colour with a pyriform carapace covered symmetrically in sharp tubercles on its dorsal surface. [1] The carapace's edges, by contrast, feature sharp spines. [1] The female holotype's carapace measures 44.2 mm (1.74 in) long and 43.5 mm (1.71 in) wide. [1] Its chelipeds bear a mix of longer spines on the inner side and smaller ones on the outer side; the chelipeds, including the chelae, are "remarkably slender". [1] The palms of its chelae are armed with spine-like tubercles tipped with tufts of setae, and its fingers are untoothed and heavily bristled. [1] Its walking legs – also slender – are especially spinose. [1] On its underside, its abdominal segments are well-developed; some are armed with tubercles, while others are smooth. [1]
P. okitoriensis is known from only one female holotype found in January 2006 off Japan's southernmost atoll, Okinotorishima, at a depth somewhere between 900 and 1,500 m (3,000 and 4,900 ft). [1] It was the 12th species of Paralomis described from Japanese waters. [1]
P. okitoriensis was described in 2019 by carcinologist Masatsune Takeda. Its name is a combination of the Japanese shorthand "Oki-Tori" for the Okinotorishima atoll where the holotype was found and the Latin suffix "-ēnsis" indicating "of or from a place". [1] [lower-alpha 1] It falls into an informal subgroup of Paralomis described by carcinologist Shane T. Ahyong which includes P. aculeata and P. spinosissima ; this subgroup is characterized by its long chelipeds and walking legs as well as short, well-spaced tubercles on its carapace. [1] [2]
The Japanese spider crab is a species of marine crab and is the biggest one that lives in the waters around Japan. At around 3.7 meters, it has the largest leg-span of any arthropod. The Japanese name for this species is taka-ashi-gani,, literally translating to “tall legs crab”. It goes through three main larval stages along with a prezoeal stage to grow to its great size.
Eumunida picta is a species of squat lobster found in the deep sea. The species is strongly associated with reefs of Lophelia pertusa, a deep-water coral, and with methane seeps. It is abundant in the western Atlantic Ocean, where it is found from Massachusetts to Colombia.
Xantho hydrophilus, the furrowed crab or Montagu's crab, is a species of crab from the family Xanthidae. It is yellowish-brown and grows to a carapace width of 70 mm (2.8 in). It is a nocturnal omnivore that lives in shallow marine waters from western Scotland to the Cape Verde Islands.
Gandalfus yunohana is a species of blind crab in the family Bythograeidae found on hydrothermal vents on the eastern edge of the Philippine Sea Plate south of Japan. Because no light penetrates to such depths, the eyes of G. yunohana are immobile and unpigmented.
Oregonia is a genus of crabs, comprising two extant species and one fossil species: It is classified in the family Oregoniidae under the spider crab superfamily Majoidea.
Oregonia bifurca, commonly known as the split-nose crab or the split-nose decorator crab, is a species of crabs belonging to the family Oregoniidae. It is a rare deep-water species that inhabits the tops of seamounts and guyots in the northeastern Pacific Ocean; from the Aleutian Islands, the Bering Sea, the Hawaiian–Emperor seamount chain, to the waters off British Columbia. It is closely related to the more common shallow-water species Oregonia gracilis, the graceful decorator crab.
Paralomis zealandica, also known as the prickly king crab, is a species of king crab which lives at a depth between 254–1,212 m (833–3,976 ft) in New Zealand. It has a spiky carapace.
Neolithodes agassizii is a species of king crab native to the Western Atlantic. They live at depths of 200–1,900 metres (660–6,230 ft), and have been found as far south as Rio de Janeiro, as far north as latitude 36°, and near the Equator. It has been found in the southwestern Caribbean Sea as well as the Gulf of Mexico.
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, eastern Australia, and possibly New Caledonia. It has been found at depths of 1,515–2,643 metres (4,970–8,671 ft).
Neolithodes vinogradovi is a species of king crab whose native habitat ranges from the Arabian Sea to the Coral Sea.
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). They have been found near Cape Point and around the Crozet and Kerguelen Islands in the subantarctic, and they are widespread in the Bellingshausen Sea on the Antarctic continental slope.
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).
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). Alongside P. zealandica, it is one of the two most common species of Paralomis in New Zealand. As of 2023, the Department of Conservation in New Zealand classifies P. dawsoni as "Naturally Uncommon".
Neolithodes indicus is a species of king crab found in the southeastern Arabian Sea.
Lithodes jessica is a species of king crab in the genus Lithodes. It is found off the coast of New Zealand on the Lord Howe Rise at depths from 680–1,100 m (2,230–3,610 ft).
Tiomanium indicum, commonly known as the Tioman crab or the white clawed mangrove crab, is a crab in the family Sesarmidae. It inhabits the Western and central Indo-Pacific ocean, including Singapore, Malaysia, Australia (Queensland), the Philippines and New Guinea. Tioman crabs are supralittoral. In Cairns, Australia they are known for moving in numbers in some seasons entering backyards and homes. This species was originally described by H. Milne Edwards in 1837 as Sesarma indicum. It was placed in a new genus Tiomanium by Serene and Soh The carapace is convex and 34 mm length. Key features that differentiate Tiomanium from Neosarmatium include a spine at the end of the upper inner margin of the cheliped palm and a spine on the upper inner angle of the carpus.
Gordonopsis is a genus of deep-sea porter crabs in the family Homolidae. The Homolidae are also known as carrier crabs or porter crabs for their fifth pereiopods, which they use to hold objects in place over the rear half of the carapace in a possible defence mechanism against predators. Species of Gordonopsis are found in deep waters of the Indo-West Pacific region. The genus was erected in 1995 by Danièle Guinot and Bertrand Richer de Forges.
Paralomis tuberipes is a species of king crab. It has been identified around Puerto Aguirre in Chile. Its depth range is unknown.
