Worldwide the Carapidae comprise two subfamilies, seven genera, about 31 described species and several undescribed species. Fifteen described species in six genera have been collected from Australian waters, with one additional genus and species from Cocos (Keeling) Islands and at least one undescribed species is known from Queensland. The names of some species are tentative, with specialists disagreeing on the appropriate name.
Members of four of the genera shelter in invertebrates, such as sea cucumbers. Some are parasitic, eating the internal organs of their host. The monotypic subfamily Pyramodontinae includes deepwater species found in the waters of the outer shelf and slope. Carapids have separate planktonic and benthic larval stages. Maximum size for the family is at least 36 cm.
The pearlfishes were reviewed by Arnold (1956). Subsequent descriptions of new species can be found in Cohen & Nielsen (1978) and Williams (1984a). Williams (1984b) treated relationships of four of the genera, and Markle & Olney (1990) discussed relationships. Life history information is provided by Trott (1970) and Robertson (1975). Relationships are discussed by Parmentier et al. (2000).
The pearlfishes are currently under study by D.F. Markle of OSUC and J. Olney of the Virginia Institute of Marine Science, USA. We thank D.F. Markle for his help with this family account.
