“The shadow of the seas”

This is  “Sikios” or “Pantelis” in Greek, the Brown Meagre (or Corb- scientific name: “Sciaena umbra”). This species spreads in the Mediterranean Sea, the Black Sea and the East Atlantic. It is usually found in rocky and sandy sea bottoms with seagrass  meadows (in fact, the iconic”Posidonia oceanica” seagrass which is not an algae but a plant) in depths from 5 to 200 meters and is preying on small fish and crustaceans (crabs, shrimp etc.). A good-looking phantom!

Sikios is an amazingly beautiful fish of the Mediterranean, with golden and silver flashes in its body and impressively bright dorsal and caudal fins – yellow with black edges and white details, while its movement is full of grace. It is mainly nocturnal fish that can be seen during the day although it prefers to remain in the holes of the rocks.

The second composer of its Latin name  “umbra” means “shadow,” and is inspired by his ability to remain invisible- partly due to the colors of his body, and partly to the perfect buoyancy he can achieve by staying motionless in shadows in the depth of the cavities where is hiding.  The fish of this species (croakers) have two bone “hammers” in their head (called “otolithi”) with which they create sounds to communicate, especially as they are very sociable and live in small groups.  If keep quite silent and can approach such a “shadow”, a diver can distinguish the special sounds, as long as he is not to late for the show!
