Identification Tips

1. 1

   Body Shape

   Look for a very deep, laterally compressed body, giving it a 'pancake-like' appearance.

2. 2

   Coloration

   Observe the silvery-gray body with potential iridescent blue hues and faint, irregular darker blotches or bars.

3. 3

   Dorsal Fin

   Note the single, long dorsal fin with prominent, strong spines in the anterior portion, which is noticeably higher than the soft-rayed posterior part.

4. 4

   Mouth and Eyes

   Identify the relatively small, pointed mouth and large eyes.

5. 5

   Pectoral Fins

   The long, pointed pectoral fins are a good distinguishing feature, often extending past the anal fin origin.
