Identification Tips

1. 1

   Body Shape and Coloration

   Look for a deep, compressed, silvery body. The presence of faint golden or yellowish horizontal lines along the flanks is a key indicator, though these can fade quickly after capture.

2. 2

   Dentition

   Examine the mouth for strong, conical teeth at the front of both jaws, followed by several rows of rounded, molar-like teeth. This dentition is adapted for crushing shells and scraping algae.

3. 3

   Fin Ray Counts

   Count the dorsal fin spines (11-12) and soft rays (10-13), and anal fin spines (3) and soft rays (8-10). These counts are consistent and aid in species identification.

4. 4

   Pectoral Fin Base

   While not always present or prominent, a dark blotch at the base of the pectoral fin can be a helpful, though not definitive, identifying mark, especially in younger individuals.
