Remark |
: |
Also commonly known as aristeid shrimps. Marine, deep water; benthic and prefer soft bottoms (Refs. 94508, 104052). Some of them are actively fished because of their large size (up to 33 cm) and high commercial value. The sexes are easily distinguished by the presence of a large copulatory organ (petasma) on the first pair of pleopods (abdominal appendages) of males, while the females have the posterior thoracic sternites modified into a large sperm receptacle process (thelycum) which holds the spermatophores or sperm sacs (usually whitish or yellowish in colour) 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 (Ref. 104052). |
