Description: The body of the spotfin croaker is elongate, but heavy forward. The
upper profile of the head is steep and slightly curved, and abruptly
rounded at the very blunt snout. The mouth is underneath the head
(subterminal). The color is silvery gray with bluish luster above and
white below. There are dark wavy lines on the side, and a large black
spot at the base of the pectoral fin.
The subterminal mouth, absence of a fleshy barbel and the large black
spot at the base of the pectoral fin distinguish spotfin croakers from all
other California croakers. Small "spotties" are sometimes confused
with small white croakers, but a count of the dorsal fin spines will
quickly separate them; the spotfin croaker has 11 or fewer (usually
10), while the white croaker as 12 to 15. So-called "golden croakers"
are nothing more than large male spotfin croakers in breeding colors.
