Procambarus

Redswamp crayfish ( Procambarus clarkii )

The genus Procambarus from the superfamily of crayfish ( Astacoidea ) is native to North and Central America, among other things includes the parthenogenetic marble cancer and the Blue Florida Cancer ( P. alleni ). Most species of the genus are found in southern North America.

With over 140 species Procambarus is the most numerous species of crayfish.

Features

All species that are included in this genus are characterized by a similar division of the body into head - thoracic area ( front body) and gegliedertem abdomen from. Both are of a thick shell ( carapace ) covered. At the front body sit five pairs of legs, the foremost pair of legs has been transformed into large claws. The remaining serve as walking legs, which also depend on gills, which breathes the crayfish.

The limbs of the first abdominal ring of the male are modified into a gonopodium. The female carries the eggs and later the newly hatched juveniles at the bottom of the abdomen. Typical of the genus are small thorn -like hooks on the base member of the walking legs of the male to hold the female during copulation ( Ischiumhaken ), the sperm storage (annulus ventralis ) of the females and matching the sperm groove of the male.

Crayfish plague

Meanwhile, many species of the genus Procambarus as neozoon are distributed worldwide. All species are potential carriers of the crayfish plague, caused by a water mold Aphanomyces astaci like illness that affects all European crayfish species and endangered.
