Within the suborder Gammaridea
it is the only family with terrestrial representatives (BOUSFIELD, 1982; LOPES; MASUNARI 2004a, b and c).
Like other peracarid crustaceans, including the Gammaridea and Isopoda, adult Caprellidea females have a brood pouch on their thoracic segments into which eggs are released.
Embryonic development of the Amphipoda has been well studied in Gammaridea (Wolff and Scholtz, 2002; Browne et al.
Some morphology-based phylogenetic studies have suggested a phylogenetic affinity between the Caprellidea and the superfamily Corophioidea, which belongs to the suborder Gammaridea
