Consigli per l'identificazione

  1. 1

    Head Spines and Cirri

    Observe the numerous spines and dermal flaps (cirri) on the head, particularly the prominent supraorbital tentacles above the eyes. The absence of a deep pit on the suborbital stay is a key identifier.

  2. 2

    Coloration and Pattern

    Note the highly variable, cryptic coloration, typically dark brown to reddish-brown with mottling and darker blotches, allowing it to blend with rocky and algal substrates.

  3. 3

    Dorsal Fin

    Count the dorsal fin spines (12) and soft rays (9-10). The continuous nature of the spiny and soft-rayed portions is characteristic.

  4. 4

    Scale Size

    Compared to other scorpionfish, Scorpaena porcus has relatively small scales, which can be a subtle but useful distinguishing feature.
