Biology

This species remains to be described but can be identified as belonging to the genus Mysidetes. 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.
