Heteromysis (from Greek heteros meaning ‘different’, and mysis, a genus name Mysis) is a genus of marine mysid crustaceans (opossum shrimps) from the family Mysidae, associated with various shallow-water invertebrates. The name describes differentiation of its pereiopods (thoracic appendages) as possible adaptation to commensal life-style. Heteromysis is one of the largest mysid genera, containing more than 100 species. The genus is distributed globally, but predominantly in tropical and subtropical waters.

Neomysis (from the Greek affix neo-, "new", and the genus name Mysis) is a genus of opossum shrimp (mysid crustacean) from the family Mysidae, distributed in the coastal zone of temperate seas of the Northern Hemisphere and South America. Several species, particularly from the West Pacific, are also found in fresh and brackish waters. The genus contains the following 18 species:

Hemisquilla is a genus of mantis shrimp, and the only genus in the family Hemisquillidae. It contains four species distributed in Australia and the Americas. Species in the genus typically eat snails, fish, rock oysters, and smaller crustaceans like crabs. They are preyed upon by larger bony fishes and cephalopods. It is the most basal living mantis shrimp lineage, and the sister group to all other mantis shrimp.

Paramysis (from the Greek affix '', "near", "beside", and the genus name Mysis'') is a genus of mysid crustaceans (Mysidacea) in family Mysidae, distributed in coastal zone of low boreal East Atlantic Ocean, Mediterranean Sea and the basins of Black Sea, Sea of Azov and Caspian Sea (Ponto-Caspian Basin).
