Spider Crab
The Majoidea are a superfamily of crabs which includes the various spider crabs. Taxonomy In "''A classification of living and fossil genera of decapod crustaceans''" De Grave and colleagues divided Majoidea into six families: * Family Epialtidae ** Subfamily Epialtinae ** Subfamily Pisinae ** Subfamily Pliosomatinae ** Subfamily Tychiinae * Family Hymenosomatidae * Family Inachidae * Family Inachoididae * Family Majidae ** Subfamily Eurynolambrinae ** Subfamily Majinae ** Subfamily Micromaiinae ** Subfamily Mithracinae ** Subfamily Planoterginae * Family Oregoniidae The classification has since been revised, with subfamilies Epialtinae and Mithracinae being elevated to families and Hymenosomatidae being moved to its own superfamily. The family composition according to the World Register of Marine Species is as follows: * family Epialtidae MacLeay, 1838 * family Inachidae MacLeay, 1838 * family Inachoididae Dana, 1851 * family Macrocheiridae Dana, 1851 * family Maj ...

Great Spider Crab
The great spider crab, ''Hyas araneus'', is a species of crab found in northeast Atlantic waters and the North Sea, usually below the tidal zone. In 1986, two specimens were captured at the South Shetland Islands off the Antarctic Peninsula The Antarctic Peninsula, known as O'Higgins Land in Chile and Tierra de San Martín in Argentina, and originally as Graham Land in the United Kingdom and the Palmer Peninsula in the United States, is the northernmost part of mainland Antarctic ..., apparently transported by human agency. It has been feared that the species would have an adverse effect on the native fauna, but there have been no further captures from the region since the 1986 specimens. The great spider crab can moult and get rid of their outer shell/skin. This can take some time but it lets them grow to great size. After they moult they are very vulnerable to predators because of a very soft exoskeleton. References Majoidea Crabs of the Atlantic Ocean Crustacean ...

Macropodia Rostrata
''Macropodia rostrata'', common names, the common spider crab, long-legged spider crab, long-legged crab, is a species of marine crab in the family Inachidae. The Macropodia Rostrata visually mimics many other types of small crabs with the exception of its long legs. By attaching algae to their thin legs, they can be confused with the stem of seaweed. This is both a defense mechanism and a predatory advantage, as unsuspecting fish will hide in seaweed beds from nearby predators. This behavior can be absent among larger crabs, and those that live at great depths like giant Japanese spider crabs. Description ''Macropodia rostrata'' has a hairy, or fuzzy appearance due to algae it applies to itself for camouflage. Both the carapace and pereiopods of this species are greyish to yellowish or reddish-brown in colour, with some specimens showing white markings. The carapace grows to a maximum length of 16 (28) mm, with the anterior part is narrowing, giving it a pear shape. The length ...

Maja Squinado
''Maja squinado'' (the European spider crab, spiny spider crab or spinous spider crab) is a species of Animal migration, migratory crab found in the north-east Atlantic Ocean, Atlantic and the Mediterranean Sea. The appearance of the European spider crab is similar to the much larger Japanese spider crab. Young The young of ''M. squinado'' are slightly longer than 1mm after hatching, and weigh approximately 0.12 mg at this time. Within 4–8 days, the larva moults numerous times, finally ending with morphological changes that presumably include the further development and increase in size of the cephalothorax. In a second phase, the Carapace grows to a length of approx. 2mm, and weighs approx. 0.3 mg. The larva then undergoes metamorphosis to the first juvenile instar, and changes its planktonic life to a Benthic zone, benthic one (living on the sea floor). Its appearance is also similar to that of the adult animal. From this stage only growth and the formation of sex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Libinia Emarginata
''Libinia emarginata'', the portly spider crab, common spider crab or nine-spined spider crab, is a species of stenohaline crab that lives on the Atlantic coast of North America. Distribution ''Libinia emarginata'' occurs from Nova Scotia to the Florida Keys and through the Gulf of Mexico. It lives at depths of up to , with exceptional records of up to . Description ''Libinia emarginata'' is roughly triangular in outline and very heavily calcified, with a carapace about long and a leg span of . The whole crab is khaki, and the carapace is covered in spines and tubercles, and, as with other decorator crabs, often clothes itself in debris and small invertebrates. Reproduction Mating takes place, and eggs are produced from June to September. The eggs are initially a bright orange-red, but turn brown during development, which takes around 25 days. The eggs then hatch as zoea larvae, and the female can produce another brood of eggs within 12 hours, unlike many other crab species ...

Japanese Spider Crab
The Japanese spider crab (''Macrocheira kaempferi'') is a species of marine crab that lives in the waters around Japan. It has the largest known leg-span of any arthropod. It goes through three main larval stages along with a prezoeal stage to grow to its great size. The genus ''Macrocheira'' contains multiple species. Two fossil species of this genus have been found, ''M. ginzanensis'' and ''M. yabei'', both from the Miocene of Japan. Its diverse taxonomic history is an important part of what these creatures are and how they evolved to be what they are today. They are sought by crab fisheries, and are considered a delicacy in Japan. Conservation efforts aim to protect these creatures and their population from overfishing. The Japanese spider crab is similar in appearance to the much smaller European spider crab ''(Maja squinado)'', though the latter, while within the same superfamily, belongs to a different family, the Majidae.
