Percnidae is a family of crabs in the superfamily 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).

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. In fact, they seem to be paraphyletic In taxonomy (general), taxonomy, a group is paraphyletic if it consists of the group's most recent common ancestor, last common ancestor and most of its descendants, excluding a few Monophyly, monophyletic subgroups. The group is said to be pa ... with respect to each other and it seems warranted to merge the Ocypodoidea into the Grapsoidea. References Extern ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
