Scales both equal one centimeter. dorsal and anal fins—lacking scales (s) vs. densely scaled (w); tooth morphology— primary teeth simple and secondary teeth bifid (s) vs. all teeth simple (w); total anal fin elements—10 or 11 (s) vs. 12 or 13 (w); general body coloration—grey, distinctly striped (s) vs. silvery, faintly striped or unstriped (w). In addition, when fi-esh or observed alive underwater, white mullet have a yellower caudal fin, which has a blackened posterior margin that is lacking in striped mullet. Selected counts and measurements (in mm) for the San Diego Mugil curema (LACM 44108-1) are: Dorsal fin IV + 8; anal fin III, 9; pectoral fin (left) 17; vertebrae 12 + 12 = 24; total length 371; head length ; pectoral fin length ; pectoral axillary scale ; anal fin base ; longest anal fin ray Two suppositions concerning the provenance of white mullet in California waters can be addressed. First, the capture of this species in 1982, 1983 and 1985, at the possible onset, during and immediately following the 1982-84 El Nifio event may be directly related to the occurrence of warm water along Baja California and California. If so, Mugil curema might be expected to make its appearance off.
