Distribution
. Epipelagic in tropical and subtropical waters of all oceans; Mediterranean Sea (
Fage, 1960
). In the eastern Pacific present in the Mexican portion of the
California
Current (
Lavaniegos & Hereu 2009
) and the SE Gulf of
California
(this study).
Remarks
. The head of this species is shorter than in the other species of the genus and the body is more robust.
Found mostly between 0 and
300 m
depth (
Vinogradov
et al
. 1996
). Not recorded previously by
Siegel-Causey (1982)
in the Gulf of
California
and not listed by García Madrigal (2007) for the tropical eastern Pacific,
S. porcella
had been consistently collected in the Mexican portion of the
California
Current (
Lavaniegos & Hereu 2009
,
Lavaniegos 2014
). During our survey it was recorded in four localities in the Gulf of
California
(
