General Description

Biology

This species was collected during the Port Phillip Bay Surveys of 1975 and again in 1995. It remains unidentified beyond the subfamily level. Opossum shrimps are so-called because they carry their eggs and young in a marsupium-like pouch. Mysids can form large shoals in shallow waters, thus are an abundant food source for both adult and juvenile coastal fish.
