Dynomenidae

	Dynomenidae Dynomenidae is a family of crabs in the superfamily Dromioidea mostly found in Madagascar. There are nineteen genera in this family: five extant and fourteen known from fossil A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in ...s: '' Acanthodromia'' A.

	Hirsutodynomene Hirsutodynomene is a genus of crabs in the family Dynomenidae. All species in this genus except the newest one belonged to the genus '' Dynomene''. These two genera form the subfamilia Dynomeninae. The type species of this genus is: '' Dynomene spinosa'' (Rathbun, 1911).

	Dromioidea Dromioidea is a superfamily of crabs mostly found in Madagascar. Dromioidea belongs the group Dromiacea, taxonomically ranked as a section, which is the most basal grouping of Brachyura crabs. Dromiacea likely diverged from the rest of Brachyura around the Late Triassic or Early Jurassic, and the earliest fossils attributable to the Dromioidea date from the Late Jurassic. The below cladogram shows Dromioidea's placement within Dromiacea: Recent studies have found that the Dromioidea family Dromiidae may be paraphyletic In taxonomy, a group is paraphyletic if it consists of the group's last common ancestor and most of its descendants, excluding a few monophyletic subgroups. The group is said to be paraphyletic ''with respect to'' the excluded subgroups. In co ... with respect to Dynomenidae.

	Dromiacea Dromiacea is a group of crabs, ranked as a section. It contains 240 extant and nearly 300 extinct species. Dromiacea is the most basal grouping of Brachyura crabs, diverging the earliest in the evolutionary history, around the Late Triassic or Early Jurassic. Below is a cladogram showing Dromiacea's placement within Brachyura: The larvae of Dromiacea resemble those of the Anomura more closely than those of other crabs. This may simply reflect their basal position in the crab phylogeny. The superfamily Eocarcinoidea, containing '' Eocarcinus'' and '' Platykotta'', was previously considered to be a member of the Dromiacea, but has since been transferred to the Anomura. The fossil record of Dromiacea reaches back at least as far as the Jurassic, and, if '' Imocaris'' is indeed a member, into the Carboniferous. Dromiacea primarily consists of two groups of superfamilies - Dromioidea and Homoloidea. See the below cladogram: Recent studies have found that some of the ...

picture info	Crab Crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting "tail" (abdomen) ( el, βραχύς , translit=brachys = short, / = tail), usually hidden entirely under the thorax. They live in all the world's oceans, in freshwater, and on land, are generally covered with a thick exoskeleton, and have a single pair of pincers. They first appeared during the Jurassic Period. Description Crabs are generally covered with a thick exoskeleton, composed primarily of highly mineralized chitin, and armed with a pair of chelae (claws). Crabs vary in size from the pea crab, a few millimeters wide, to the Japanese spider crab, with a leg span up to . Several other groups of crustaceans with similar appearances – such as king crabs and porcelain crabs – are not true crabs, but have evolved features similar to true crabs through a process known as carcinisation. Environment Crabs are found in all of the world's oceans, as well as in fres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Danièle Guinot Danièle Guinot (born 1933) is a French biologist, an emeritus professor at the Muséum national d'histoire naturelle in France, known for her research on crabs. Biography Guinot was born in eastern France and educated at the University of Montpellier and the University of Paris, finishing her studies in 1955. She then joined the Muséum national d'histoire naturelle as a research assistant; she remained there for the rest of her career. She earned a doctorate from Pierre and Marie Curie University in 1977. Research Guinot carried out several studies of crabs from exotic environments, including deep-sea crabs from the Indo-West Pacific bathyal zone and from hydrothermal vents, and crabs living in caves in Papua New Guinea. Her doctoral thesis proposed a new classification system for certain crabs based on the position of their reproductive organs. In later studies, she became particularly interested in crab behavior, including stridulation Stridulation is the act of producing s ...
