Consigli per l'identificazione

  1. 1

    Juvenile Fin Filaments

    The most striking feature of juveniles is the presence of extremely long, trailing filaments from the dorsal and anal fins. These are unmistakable.

  2. 2

    Body Shape

    The highly compressed, deep, and almost disc-like body shape, especially in younger individuals, is a key identifier.

  3. 3

    Absence of Scutes

    Unlike many other members of the Carangidae family, Alectis ciliaris lacks prominent scutes (hard, bony plates) along the lateral line, which feels smooth to the touch.

  4. 4

    Head Profile

    The steeply rising, almost vertical head profile is characteristic, particularly in adults.
