Particularly abundant in coastal creeks and floodplains where it is supported by a certain salinity level. It is vulnerable to a trematode parasite which induces a characteristic cutaneous reaction. Reproduction in captivity has been successful (Ref. 12225). Maximum length questionable (Ref. 38376).
