The Microcerberidae are a family of isopod crustaceans. They are less than 2mm long, and live interstitially in shallow marine or freshwater sand habitats.[1]
Marine microcerberids comprise the main part species diversity, but are very alike. As a group, they have very broad distribution:
Freshwater taxa are less abundant in species number (only 12 species), but are more morphologically diverse and include seven or eight genera. They have these distributions:
