Distribution
Most members of the family Panopeidae live in the Atlantic Ocean or eastern Pacific Ocean. Only one species occurs in Australian waters – Homoioplax haswelli.
Ecology
The various genera of Panopeidae are morphologically similar, partly as a result of many instances of convergent evolution to similar habitats and food preferences.
Crabs of the family Panopeidae are all free-living (not commensal or parasitic), and typically live in soft-bottomed parts of the ocean, lending them the common name "mud crabs" (a name also shared by other organisms). They burrow into the sediment and feed on a variety of marine invertebrates.
Genera
