Mysida is an order of small, shrimp -like crustaceans in the malacostracan superorder Peracarida. Their common name opossum shrimps stems from the presence of a brood pouch or "marsupium" in females. The fact that the larvae are reared in this pouch and are not free-swimming characterises the order.

Mysids and stygiomysids are benthopelagic, found above various bottom habitats during daytime and vertically migrating during night. They can constitute an important food source for benthic and pelagic fishes. They are predominantly omnivorous filter feeders and predators.

2023年6月1日 · Mysids have a high ecological importance, particularly by their role in food chains. The rapid response of mysids to ecosystem alterations makes them an effective predictor of climate changes. Mysids may contribute to the transfer of metals and MPs to higher trophic levels.

2016年7月1日 · Mysids, also known as “opossum shrimps,” are shrimp-like crustaceans that occur in vast numbers throughout the waters of the world.

2016年8月1日 · Mysids are abundant, highly migratory, epibenthic fauna (Jumars 2007; Wittman et al. 2012) found in both freshwater and marine environments.

Mysids are sometimes known as opossum shrimps because of the marsupium, or external pouch, formed by specially developed plates on the inner sides of the thoracic limbs of adult females. Most mysids are fairly small, between 0.39 and 1.18 in (10 and 30 mm) long.

In this article we present a biogeographical assessment of species diversity within the Mysida (Crustacea: Malacostraca: Peracarida) from inland waters. Inland species represent 6.7% (72 species) of mysid diversity.

Mysids have a high ecological importance, particularly by their role in marine food chains as a link between the benthic and pelagic realms. Here we describe the relevant taxonomy, ecological aspects such as distribution and production, and their potential as ideal test organisms for environmental r …

Mysids are sometimes called "opossum shrimps" because the females of some species have leg bases with well developed plates. These plates form an enclosed chamber, or brood pouch, under the thorax. This pouch, called the marsupium, protects the eggs and young and is similar in function to the marsupia of opossums, kangaroos, and other marsupial ...
