Remark |
: |
All of the representatives of this family are marine, benthic, predominantly tropical and subtropical, occurring on the continental shelf in depths between 3 and 70m in the area. The sexes are easily distinguished by the presence of a large copulatory organ (petasma) on the first pair of pleopods of males, while females have the posterior thoracic sternites modified into a large sperm receptacle process (thelycum) which holds the spermatophores or sperm sacs after mating. The eggs are small and numerous, and are released directly into the water and not retained on the female abdomen. The larvae are planktonic and have the nauplius stage. The species are of minor commercial interest in the area (Ref. 104052). |
