Amphipoda is an order of malacostracan crustaceans with no carapace and generally with laterally compressed bodies. Amphipods 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. They are mostly marine animals, but are found in almost all aquatic environments. Some 1,900 species live in fresh water, and the order also includes the terrestrial sandhoppers such as Talitrus saltator.

Etymology and names

The name Amphipoda comes, via the New Latin amphipoda, from the Greek roots ἀμφί ("on both/all sides") and πούς ("foot"). This contrasts with the related Isopoda, which have a single kind of thoracic leg.[3] Particularly among anglers, amphipods are known as freshwater shrimp, scuds or sideswimmers.[4][5]

The body of an amphipod is divided into 13 segments, which can be grouped into a head, a thorax and an abdomen.[4]

The head is fused to the thorax, and bears two pairs of antennae and one pair of sessile compound eyes.[6] It also carries the mouthparts, but these are mostly concealed.[7]

The thorax and abdomen are usually quite distinct and bear different kinds of legs; they are typically laterally compressed, and there is no carapace.[6] The thorax bears eight pairs of uniramous appendages, the first of which are used as accessory mouthparts; the next four pairs are directed forwards, and the last three pairs are directed backwards.[6] Gills are present on the thoracic segments, and there is an open circulatory system with a heart, using haemocyanin to carry oxygen in the haemolymph to the tissues. The uptake and excretion of salts is controlled by special glands on the antennae.[4]

The abdomen is divided into two parts: the pleosome which bears swimming legs; and the urosome, which comprises a telson and three pairs of uropods which do not form a tail fan as they do in animals such as true shrimp.[6]
Amphipods are typically less than 10 millimetres (0.4 in) long

Amphipods are typically less than 10 millimetres (0.4 in) long, but the largest recorded living amphipods were 28 centimetres (11 in) long, and were photographed at a depth of 5,300 metres (17,400 ft) in the Pacific Ocean.[8] Samples retrieved from the stomach of a black-footed albatross had a reconstructed length of 34 centimetres (13 in); it was assigned to the same species, Alicella gigantea.[9] The smallest known amphipods are less than 1 millimetre (0.04 in) long.[10] The size of amphipods is limited by the availability of dissolved oxygen, such that the amphipods in Lake Titicaca at an altitude of 3,800 metres (12,500 ft) can only grow up to 22 millimetres (0.87 in), compared to lengths of 90 millimetres (3.5 in) in Lake Baikal at 455 metres (1,500 ft).[11]

Some amphipods exhibit sexual dimorphism. In dimorphic species, males are usually larger than females, although this is reversed in the genus Crangonyx.[12]
Reproduction and life cycle

Amphipods engage in amplexus, a precopulatory guarding behavior in which males will grasp a female with their gnathopods (enlarged appendages used for feeding) and carry the female held against their ventral surface. Amplexus can last from two to over fifteen days, depending on water temperature, and ends when the female molts, at which point her eggs are ready for fertilisation.[12]

Mature females bear a marsupium, or brood pouch, which holds her eggs while they are fertilised,[4] and until the young are ready to hatch.[6] As a female ages, she produces more eggs in each brood. Mortality is around 25–50% for the eggs.[4] There are no larval stages; the eggs hatch directly into a juvenile form, and sexual maturity is generally reached after 6 moults.[4] Some species have been known to eat their own exuviae after moulting[4]
Diversity and classification

Over 9,950 species of amphipods are currently recognised.[13] Traditionally they were placed in the four suborders Gammaridea (which contained the majority of taxa, including all the freshwater and terrestrial species[7]), Caprellidea, Hyperiidea, and Ingolfiellidea (the last with only 40 species[14]).

The classification of the Amphipoda is however being rearranged to better reflect their phylogeny, the relationships within the suborder Gammaridea having suffered from the most confusion. A new classification has been developed in the works of Lowry & Myers, where a new large suborder Senticaudata was split off from the Gammaridea in 2013.[15][16] That taxon, which also encompasses the previous Caprellidea, now comprises over half of the known amphipod species.[13] The more recent work of Copilaş-Ciocianu et al. in 2019 (based on COI, H3, 18S and 28S molecular data) still supports the main suborders Amphilochidea, Hyperiidea and Senticaudata, but suggests some reshuffling.[17] The classification given below, from the rank of suborder down to superfamily, however still represents the traditional division as given in Martin & Davis (2001),[18] except that superfamilies are recognised here[according to whom?] within the Gammaridea.









Ampelisca brevicornis (Gammaridea: Ampeliscidae)

Fossil record

Amphipods are thought to have originated in the Lower Carboniferous. Despite the group's age, however, the fossil record of the order Amphipoda is meagre, comprising specimens of one species from the Lower Cretaceous (Hauterivian) Weald Clay (United Kingdom)[20] and 12 species dating back only as far as the Upper Eocene, where they have been found in Baltic amber.[21][22]
Talitrus saltator is an abundant animal of sandy beaches around Europe.

Amphipods are found in almost all aquatic environments, from fresh water to water with twice the salinity of sea water[4] and even in the Challenger Deep, the deepest known point in the ocean.[23] They are almost always an important component of aquatic ecosystems,[24] often acting as mesograzers.[25] Most species in the suborder Gammaridea are epibenthic, although they are often collected in plankton samples. Members of the Hyperiidea are all planktonic and marine.[6] Many are symbionts of gelatinous animals, including salps, medusae, siphonophores, colonial radiolarians and ctenophores, and most hyperiids are associated with gelatinous animals during some part of their life cycle.[26] Some 1,900 species, or 20% of the total amphipod diversity, live in fresh water or other non-marine waters. Notably rich endemic amphipod faunas are found in the ancient Lake Baikal and waters of the Caspian Sea basin.[27]

The landhoppers of the family Talitridae (which also includes semi-terrestrial and marine animals) are terrestrial, living in damp environments such as leaf litter.[28] Landhoppers have a wide distribution in areas that were formerly part of Gondwanaland, but have colonised parts of Europe and North America in recent times.

Around 750 species in 160 genera and 30 families are troglobitic, and are found in almost all suitable habitats, but with their centres of diversity in the Mediterranean Basin, southeastern North America and the Caribbean.[29]

In populations found in Benthic ecosystems, amphipods play an essential role in controlling brown algae growth.[25] The mesograzer behaviour of amphipods greatly contributes to the suppression of brown algal dominance in the absence of amphipod predators.[25] Amphipods display a strong preference for brown algae in Benthic ecosystems, but due to removal of mesograzers by predators such as fish, brown algae is able to dominate these communities over green and red algae species.[25]

Compared to other crustacean groups, such as the Isopoda, Rhizocephala or Copepoda, relatively few amphipods are parasitic on other animals. The most notable example of parasitic amphipods are the whale lice (family Cyamidae). Unlike other amphipods, these are dorso-ventrally flattened, and have large, strong claws, with which they attach themselves to baleen whales. They are the only parasitic crustaceans which cannot swim during any part of their life cycle.[30]
Foraging behaviour

Most amphipods are detritivores or scavengers,[4] with some being grazers of algae, omnivores or predators[6] of small insects and crustaceans.[4] Food is grasped with the front two pairs of legs, which are armed with large claws.[4] More immobile species of amphipods eat higher quantities of less nutritious food rather than actively seeking more nutritious food.[31] This is a type of compensatory feeding.[31] This behaviour may have evolved to minimise predation risk when searching for other foods.[31] Ampithoe longimana, for example, is more sedentary than other species and have been observed to remain on host plants longer.[31] In fact, when presented with both high- and low-nutrition food options, the sedentary species Ampithoe longimana does not distinguish between the two options.[31] Other amphipod species, such as Gammarus mucronatus and Elasmopus levis, which have superior predator avoidance and are more mobile, are better able to pursue different food sources.[31] In species without the compensatory feeding ability, survivorship, fertility, and growth can be strongly negatively affected in the absence of high-quality food.[31] Compensatory feeding may also explain the year-round presence of A. longimana in certain waters.[32] Because algal presence changes throughout the year in certain communities, the evolution of flexible feeding techniques such as compensatory feeding may have been beneficial to survival.[32]

Ampithoe longimana has been observed to avoid certain compounds when foraging for food.[33] In response to this avoidance, species of seaweed such as Dictyopteris membranacea or Dictyopteris hoytii have evolved to produce C11 sulfur compounds and C-9 oxo-acids in their bodies as defense mechanisms that specifically deter amphipods instead of deterrence to consumption by other predators.[33]

The incidence of cannibalism and intraguild predation is relatively high in some species,[34] although adults may decrease cannibalistic behaviour directed at juveniles when they are likely to encounter their own offspring.[35] In addition to age, the sex seems to affect cannibalistic behaviour as males cannibalised newly moulted females less than males.[34]

They have, rarely, been identified as feeding on humans; in Melbourne in 2017 a boy who stood in the sea for about half an hour had severe bleeding from wounds on his legs that did not coagulate easily. This was found to have been caused by "sea fleas" identified as lysianassid amphipods, possibly in a feeding group. Their bites are not venomous and do not cause lasting damage.[36]
