Dicas de identificação

1. 1

   Dorsal Stripes

   Look for the distinctive wavy, dark vertical bars on the iridescent blue-green dorsal surface. These do not extend below the lateral line.

2. 2

   Finlets

   Count the five small finlets behind both the second dorsal and anal fins. This is a key characteristic of Scombridae.

3. 3

   Absence of Swim Bladder

   Unlike many fish, Scomber scombrus lacks a swim bladder, requiring constant swimming to maintain buoyancy. This is not an external feature but a defining biological trait.

4. 4

   Size

   Adults typically range from 30-50 cm (12-20 inches) in length, with a maximum recorded length of about 60 cm (24 inches) and weight of 3.4 kg (7.5 lbs).
