Percnon Gibbesi
''Percnon gibbesi'' is a species of crab. It is one of at least two species commonly called "Sally Lightfoot" (the other being the semi-terrestrial ''Grapsus grapsus'' from the Pacific coast of the Americas), and is also referred to as the ''nimble spray crab'' or ''urchin crab''. It has been described as "the most invasive decapod species to enter the Mediterranean". Description Adults have a carapace wide, and legs with yellow rings at the joints. Each of the five pairs of walking legs has a row of spines along the leading edge. Females carrying eggs have been caught off West Africa between February and April and August; the larvae which hatch from them are planktonic and long-lived, which may contribute to the species' invasiveness. Taxonomy The genus '' Percnon'' is currently "doubtfully placed" in the family Plagusiidae, and it has also been included in the family Grapsidae. Distribution ''P. gibbesi'' is one of the most widespread grapsid crabs, being found on both si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plagusiidae
The Plagusiidae are a family of crabs, formerly treated as a subfamily of the family Grapsidae, but have since been considered sufficiently distinct to be a family in their own right. The family Plagusiidae includes the subfamily Plagusiinae, comprising the genera ''Percnon'' and '' Plagusia'', which constitute a widespread group of litophilic, intertidal and subtidal crabs that are notorious for their speed and their agility. Six genera are included in the family: *''Davusia'' Guinot, 2007 *'' Euchirograpsus'' H. Milne-Edwards, 1853 *'' Guinusia'' Schubart & Cuesta, 2010 *'' Miersiograpsus'' Türkay, 1978 *''Percnon ''Percnon'' is a genus of crabs.

Grapsidae
The Grapsidae are a family of crabs known variously as marsh crabs, shore crabs, or talon crabs. The family has not been confirmed to form a monophyletic group and some taxa may belong in other families. They are found along the shore among rocks, in estuaries, marshes, and in some cases pelagic among drifting seaweeds and flotsam. Genera A number of taxa, formerly treated as subfamilies of the family Grapsidae are now considered families in their own right, including the Varunidae and Plagusiidae. Ten genera remain in the family, two of them known only from fossils: *''Geograpsus'' Stimpson, 1858 *'' Goniopsis'' De Haan, 1833 *''Grapsus'' Lamarck, 1801 *'' Leptograpsodes'' Montgomery, 1931 *''Leptograpsus'' H.

Grapsoidea
The Grapsoidea are a superfamily of crabs; they are well known and contain many taxa which are terrestrial (land-living), semiterrestrial (taking to the sea only for reproduction), or limnic (living in fresh water). Another well-known member with a more conventional lifestyle is the Chinese mitten crab, ''Eriocheir sinensis''. The delimitation of the Grapsidae and Plagusiidae is in need of revision; the latter at least is not monophyletic. The same apparently holds true for several genera in the Sesarmidae. The closest living relatives of the Grapsoidea are the Ocypodoidea The Ocypodoidea, or ocypoid crabs, are a superfamily of crabs, named after the genus '' Ocypode''. It contains over 300 extant species in these eight families: * Camptandriidae Stimpson, 1858 * Dotillidae Stimpson, 1858 * Heloeciidae H. Miln .... In fact, they seem to be paraphyletic with respect to each other and it seems warranted to merge the Ocypodoidea into the Grapsoidea. References Exter ...

Johann Friedrich Wilhelm Herbst
Johann Friedrich Wilhelm Herbst (1 November 1743 – 5 November 1807) was a German naturalist and entomologist from Petershagen, Minden-Ravensberg. He served as a chaplain in the Prussian army. His marriage in Berlin, 1770, with Euphrosyne Luise Sophie (1742–1805), daughter of the Prussian ''Hofrat'' Libert Waldschmidt seems to have been childless. He was the joint editor, with , of ''Naturgeschichte der in- und ausländischen Insekten'' (1785–1806, 10 volumes), which was one of the first attempts at a complete survey of the order [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henri Milne-Edwards
Henri Milne-Edwards (23 October 1800 – 29 July 1885) was an eminent French zoologist. Biography Henri Milne-Edwards was the 27th child of William Edwards, an English planter and colonel of the militia in Jamaica and Elisabeth Vaux, a Frenchwoman. Henri was born in Bruges, in present-day Belgium, where his parents had retired; Bruges was then a part of the newborn French Republic. His father had been jailed for several years for helping some Englishmen in their escape to their country. Henri spent most of his life in France. He was brought up in Paris by his older brother Guillaume Frederic Edwards (1777–1842), a distinguished physiologist and ethnologist. His father was released after the fall of Napoleon. The whole family then moved to Paris. At first he turned his attention to medicine, in which he graduated as an MD at Paris in 1823. His passion for natural history soon prevailed, and he gave himself up to the study of the lower forms of animal life. He became a stude ...
