Amphipoda (/ æ m ˈ f ɪ p ə d ə /) is an order of malacostracan crustaceans with no carapace and generally with laterally compressed bodies. Amphipods (/ ˈ æ m f ɪ p ɒ d z /) range in size from 1 to 340 millimetres (0.039 to 13 in) and are mostly detritivores or scavengers.
Senticaudata was split off from the traditional suborder Gammaridea by James K. Lowry and Alan A. Myers in 2013, as a part of a process of reorganising the higher taxonomy of amphipods. It now also encompasses the previously recognized Caprellidea and Corophiidea . [ 3 ]
The Ampeliscidae are a family of amphipods, distinct enough to warrant placement in a monotypic superfamily Ampeliscoidea. [1] They are benthic, found at the bottom of seas and oceans. They are distributed worldwide, and are often abundant in areas with fine sediments. [2] They live in infaunal tubes, constructed from "amphipod silk" and ...
Phronima species live in the pelagic zone of the deep ocean. Their bodies are semitransparent. Although commonly known as parasites, they are more technically correctly called parasitoids. [2] Instead of constantly feeding on a live host, females attack salps, using their mouths and claws to eat the animal and hollow out its gelatinous shell. [3]
Gammarus is an amphipod crustacean genus in the family Gammaridae.It contains more than 200 described species, making it one of the most species-rich genera of crustaceans. [2]
Talitridae is a family of amphipods. Terrestrial species are often referred to as landhoppers and beach dwellers are called sandhoppers or sand fleas. The name sand flea is misleading, though, because these talitrid amphipods are not siphonapterans (true fleas), do not bite people, and are not limited to sandy beaches. [1]
Themisto gaudichaudii matures at lengths between 6 and 12 mm (0.24 and 0.47 in) or more. Reproduction can be nearly continuous but becomes more seasonal at higher latitudes.
Hyalella azteca has body plan similar to most amphipods and is a classic freshwater example of the order. They grow to a length of 3–8 millimetres (0.12–0.31 in), with males being larger than females. [1] Their color is variable, but the most frequent hues are white, green and brown. [1]
