Alicella gigantea
Alicella gigantea is a giant species of amphipod inhabiting the deep sea, which is sometimes referred to as the "supergiant amphipod"; these crustaceans may reach in length. The only species within the genus Alicella, the species is white in colour and is distinguished from closely related amphipods mainly by size, though subtle anatomical differences can be used for small specimens. They live at depths of around , and their large body size is often presented as an example of abyssal gigantism. Genetic studies into the species have found that it has an exceptionally large genome, which may be

Ampeliscidae
The Ampeliscidae are a family of amphipods, distinct enough to warrant placement in a monotypic superfamily Ampeliscoidea. They are benthic, found at the bottom of seas and oceans. They are distributed worldwide, and are often abundant in areas with fine sediments. They live in infaunal tubes, constructed from "amphipod silk" and sediment.
Leucothoidae
Leucothoidae is a family of amphipods. It contains 138 species in 5 genera:

Before this transformation was recognised in 1983, females and immature males were described in the genus Leucothoides (Leucothoidae), and mature males were described in the genera Anamixis, Paran

Paracalliope
Paracalliope is a genus of amphipod crustaceans that live in Australasia. They include the most common freshwater amphipods in New Zealand, where they are particularly frequent in slow-flowing reaches of rivers. They shelter among weed beds and are important prey items for fish such as the New Zealand smelt, Retropinna retropinna, which are in turn important prey for the freshwater eels Anguilla australis and Anguilla dieffenbachii. Paracalliope acts as an intermediate host for the nematode Hedruris spinigera, which can thus reach their primary host, the eel.
