Dicas de identificação

1. 1

   Body Markings

   Adult Cavala-Serra (King Mackerel) typically lack spots or stripes on their sides, appearing uniformly silvery below the iridescent blue-green back. This is a key differentiator from Spanish Mackerel (Scomberomorus maculatus) which have distinct golden-bronze spots.

2. 2

   Lateral Line

   Observe the lateral line. In S. cavalla, it makes a sharp, distinct dip below the second dorsal fin, then continues relatively straight to the caudal fin. In contrast, the lateral line of Spanish Mackerel has a more gradual curve.

3. 3

   First Dorsal Fin

   The anterior portion of the first dorsal fin is often dark or black, especially in younger individuals, and the fin itself is relatively long.

4. 4

   Size

   Cavala-Serra are generally much larger than Spanish Mackerel. While juveniles can be confused, an adult Cavala-Serra will be significantly larger, often exceeding 10 kg (22 lbs) and 1 meter (3.3 feet) in length.

5. 5

   Teeth

   Possesses large, triangular, compressed teeth, which are visible when the mouth is open. These are characteristic of its predatory nature.
