	Amphipods are a type of [[crustacean]] ~~which includes~~ groups such as crabs, lobsters and shrimp [1]. Amphipods can be found in both marine and terrestrial environments with currently 10,753 known species [1]. In aquatic environments, amphipods are often referred to as as scuds, shrimp, or side swimmers [1]. Terrestrial species may be called land hoppers or beach/sand flies [1]. Amphipods are often considered keystone species due to their high population densities and their significant role in food webs [3].

	Amphipods can range from 1 to 340 millimeters [2] with a laterally compressed, segmented body and prominent antennae [4]. Amphipods lack a carapace which is the hard upper shell ~~that be~~ seen on crayfish or lobsters [5]. Amphipoda ~~also~~ means "different feet", referring to their three pairs of pleopods and three pairs of uropods, ~~whereas~~ [[Isopods]], a related group of crustaceans, means "same feet" [1]. Most amphipods are [[detritivores]], feeding on decaying plant and animal matter ~~which~~ plays a vital role in ecosystems ~~by breaking~~ down organic material [5]. Similar to crayfish ~~and lobsters~~, amphipods must periodically molt their exoskeleton in order to grow [6].		Amphipods can range from 1 to 340 millimeters long [2], with a laterally compressed, segmented body and prominent antennae [4]. Amphipods lack a carapace, which is the hard upper shell seen on crayfish or lobsters [5]. Amphipoda means "different feet", referring to their three pairs of pleopods and three pairs of uropods. Conversely, [[Isopods]], a related group of crustaceans, means "same feet" [1]. Most amphipods are [[detritivores]], feeding on decaying plant and animal matter. This feeding style plays a vital role in ecosystems, as it breaks down organic material [5]. Similar to crayfish, amphipods must periodically molt their exoskeleton in order to grow [6].

	'''Aquatic:''' Aquatic amphipods can be found in both marine and freshwater environments and are often found at the bottom of the substrate [5]. Some ~~of the~~ aquatic ~~species~~ may be seen burrowing in the substrate, creating small tunnels or depressions where they can hide from predators and forage for food [5]. In doing so, this behavior also plays a role in sediment turnover [5].

Some aquatic amphipods may be seen burrowing in the substrate, creating small tunnels or depressions where they can hide from predators and forage for food [5]. In doing so, this behavior also plays a role in sediment turnover [5].

	'''Terrestrial:''' Terrestrial amphipods live on the top half inch of [[soil]], relying heavily on ~~the~~ moisture to survive [6]. Amphipods do not contain a waxy layer on their exoskeleton, therefore ~~they are~~ prone to desiccation in dry environments ~~due to significant water losses[6]~~. Significant changes in soil moisture or habitat disturbance can quickly impact their populations.

	==Life Cycle==		==Life Cycle==
	Most amphipod species complete their life cycle in one year or less [6]. Female amphipods can produce hundreds of eggs within a single brood [6]. These eggs are kept in a pouch called a marsupium, located on the underside of the female offering protection as the eggs develop [7]. Depending on the species and water temperature, it may take 1 to 20 weeks for the eggs to fully develop [7]. Once the eggs hatch, the juvenile amphipods look like small versions of the adults and become sexually mature after growing and molting several times [6].

	Amphipods are considered secondary producers within aquatic and terrestrial food webs [8]. They primarily feed on organic materials such as [[algae]] and detritus which helps recycle nutrients [8]. Additionally, amphipods serve as a major food source for certain juvenile fish species [8].		Amphipods are considered secondary producers within aquatic and terrestrial food webs [8].
