This family includes four genera of 'spearers', Pseudosquilla, Pseudosquillisma, Pseudosquillanaand Raoulserenea, all recorded from Australia. Pseudosquillids occupy a diverse range of habitats, from rocky and coral reefs to sand or mudflats and seagrass beds. Keys to all genera and species of the Pseudosquillidae are provided by Ahyong (2001).
