Callianassa

Callianassa is a genus of mud shrimps, in the family Callianassidae. Three of the species in this genus (C. candida, C. tyrrhena and C. whitei) have been split off into a new genus, Pestarella, while others such as Callianassa filholi have been moved to Biffarius. The genus is named after the Nereid of the Greco-Roman mythology.
