Life cycle and mating behavior Chín muồi sinh dục | Sự tái sinh sản | Đẻ trứng | Các trứng | Sự sinh sản | Ấu trùng

Members of the order Decapoda are mostly gonochoric. Mating behavior: Precopulatory courtship ritual is common (through olfactory and tactile cues); usually indirect sperm transfer (Ref. 833). Berried females migrate from littoral areas to more saline and deeper water (8-10 m) until hatching of eggs; afterwhich, they go back to moult and copulate (Ref. 128197). Larger females can breed twice or thrice annually (Ref. 128203).
