Lysmata
cleaner shrimp, peppermint shrimp
Lysmata is a genus of marine caridean shrimp distinguished by its unique sexual system of protandric simultaneous hermaphroditism. The genus includes two main ecological groups: cleaner shrimp that live in pairs and remove parasites from fish, and peppermint shrimp that often live in aggregations and consume pest anemones. All studied species begin life as males before maturing into functional simultaneous hermaphrodites capable of both producing and fertilizing eggs. Members of this genus are heavily targeted by the ornamental aquarium trade, with some species commanding high prices.

Lysmata californica
red rock shrimp, lined shrimp
Lysmata californica is a caridean shrimp species native to the East Pacific, commonly known as the red rock shrimp or lined shrimp. It inhabits shallow coastal ecosystems of Southern California where it plays a role in benthic communities. The species has been studied for its behavioral responses to environmental stressors including ocean acidification and warming.

Palaemon vulgaris
Marsh Grass Shrimp, Common American Prawn, Common Grass Shrimp, Marsh Shrimp
Palaemon vulgaris is a small, transparent caridean shrimp native to the western Atlantic Ocean. Adults reach less than 5 cm in length and display distinctive orange pigmentation on the eyestalks. The species has been studied for its specialized swimming mechanics, employing metachronal beating of pleopods and drag-reducing mechanisms during locomotion. It occupies coastal and estuarine habitats from Cape Cod Bay to the Gulf of Mexico.

Pandalidae
pandalid shrimp
Pandalidae is a family of caridean shrimp commonly known as pandalid shrimp, characterized by two distinctive morphological features: a subdivided carpus on the second pereiopod and the absence of chelae (claws) on the first pereiopod. Members of this family are predominantly cold-water species, with tropical representation occurring primarily through deep-sea forms. The family holds significant commercial value, as many species are edible and support important fisheries. The genus Physetocaris, formerly included in Pandalidae, has been reclassified into its own family Physetocarididae.
