Sexual dismorphism : As a general rule, female are larger than males. The segments making up the abdomen are lengthened towards the underside to offer protection to eggs that are held by the pleopods (swimmerets located under the abdomen). The antennules (shortest set of antenna) of the male are longer than those of the females. The cephalothorax is rounder in females (detail photographed on the male and the female).
Reproduction : Simple, it doesn’t need any salt water larval stage. Every two to three weeks the female carries thirty eggs for an incubation period of four to six weeks. Stimulation can be improved by lowering the water temperature to 18 for a few weeks then bringing it gradually back to 25. The young are sexually mature after 4 months.
