Identification
The body of white sea bass is elongated and somewhat compressed. Along the middle of the belly, between the abdomen and the base of the pelvic fins, there is a characteristic upbeat ridge. The head is pointed and slightly flattened. The mouth is large, with several small teeth and a protruding lower jaw. The first dorsal fin has nine spines, the second - two spines and 20 soft rays. The anal fin has two spines and 10 soft rays. There are no spines on the chin. Its coloration is bluish-gray on top with dark speckles and becomes silvery underneath. The white sea bass can be distinguished from its Atlantic relatives by the absence of fangs. It is the only California croaker that weighs more than 20 pounds. It is easiest to distinguish from others by the presence of a ridge running the length of its belly.
