Abstract

During July 2017, eight specimens of the crab Portunus segnis (Forskål, 1775), infested by Chelonibia patula (Ranzani, 1818) were collected in the Gulf of Gabès (South-East of Tunisia). The barnacles were attached to the carapace and clamps of their hosts. This cosmopolitan barnacle species is reported for the first time, hosted by P. segnis in the Gulf of Gabès. The large sized crabs host more barnacles than small crabs. Males are more infested by barnacles than females.
