Amphipoda (/ æmˈfɪpədə /) is an order of malacostracan crustaceans with no carapace and generally with laterally compressed bodies. Amphipods (/ ˈæmfɪpɒdz /) range in size from 1 to 340 millimetres (0.039 to 13 in) and are mostly detritivores or scavengers. There are more than 9,900 amphipod species so far described.

Amphipod, any member of the invertebrate order Amphipoda (class Crustacea) inhabiting all parts of the sea, lakes, rivers, sand beaches, caves, and moist (warm) habitats on many tropical islands. Marine amphipods have been found at depths of more than 9,100 m (30,000 feet).

Amphipods are important herbivores, detritivores, micropredators and scavengers in most environments and they form an important component of marine and freshwater ecosystems.

2024年9月5日 · Amphipods, belonging to the order Amphipoda, are a diverse group of crustaceans within the class Malacostraca, which also includes crabs, lobsters, and shrimp. These small, shrimp-like organisms are distinguished by their laterally compressed bodies, which consist of three distinct regions: the head, thorax, and abdomen.

Amphipoda, commonly called scuds or sideswimmers (Figure 31.1), are diverse and common in both surface and subterranean freshwater habitats. With approximately 1900 described species (Väinölä et al., 2008), amphipods constitute the most diverse and ubiquitous group of peracarids in …

Amphipod is any of the small, largely marine, shrimp-like crustaceans comprising the arthropod order Amphipoda. Included among the amphipods are the abundant sand-hoppers or beach-fleas, the predaceous ghost shrimp, and the whale ectoparasites Cyamus.

Amphipods are elongate and more or less compressed laterally. They do not have a carapace (the hard covering of the thorax common in other crustacea), and seven (rarely six) of the thoracic segments are distinct and bear leglike appendages.

Amphipods are a diverse group of crustacean arthropods found in virtually all habitats of the world. Most are marine but 1,200 species are known to inhabit fresh water, and almost 100 species are terrestrial. Most amphipods are benthic, living in burrows of mud or among detritus. Some live in fresh water among decaying leaves.
