The Cotylorhiza tuberculata beautiful and elegant lends itself well to underwater photography and video footage, making itself admired by all those who love the sea. This video is particularly interesting because I have never encountered a Mediterranean Cassiopeia stormed and completely surrounded by so many fry of Caranx crysos. The jellyfish does not seem at all disturbed by the presence of many “friends” who take advantage of its hospitality. The show is exciting. Cassiopea mediterranea incubatrice di Caranx crysos

I remind you that the Cotylorhiza tuberculata is a species of jellyfish, of the phylum Cnidaria, also known as the Mediterranean jelly. It is commonly found in the Mediterranean Sea, Aegean Sea, and Adriatic Sea. It can reach 40 cm in diameter. It seems that this jellyfish’s sting has very little or no effect on humans. The cnidarian’s smooth, elevated central dome is surrounded by a gutter-like ring. Its marginal lappets are elongated and subrectangular. Each moutharm bifurcates near its base and branches several times. In addition to some larger appendages, there are many short, club-shaped ones that bear disk-like ends.

A curious aspect is that this type of jellyfish are always accompanied by some minnows, such as mackerel, cod, etc., which, being immunized against the stinging poison, seek shelter among their tentacles in case of danger. Cassiopea mediterranea incubatrice di Caranx crysos

Caranx crysos is a fish belonging to the Carangidae family, class Actinopterygii, of the Perciformes order that generally inhabit the tropical seas. These fish generally travel in pairs or small groups. However, we know that, like other species, they entered the Mediterranean through the Suez Canal and now we find them not only in Sicily and Sardinia but also off the Tyrrhenian coast.

During the juvenile phase they present different vertical bars and a golden yellow color. They make pelagic life and gather around floating objects like tree trunks, palm leaves or even around jellyfish or inside the umbrella of jellyfish. Later with the growth they migrate deep into the reefs.
