Biology     Glossary (e.g. epibenthic)

Occurs at depths from 2 to 20 m in bottom soft mud. Adults are found in marine environment. Juveniles are found in estuarine environment. Live in tropical climate (Ref. 8). In general, the majority of penaeids are omnivorous or detritus feeders (Ref. 105082).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Members of the order Decapoda are mostly gonochoric. Mating behavior: Precopulatory courtship ritual is common (through olfactory and tactile cues); usually indirect sperm transfer.
