Also other young trevally, for example the amberjack, have the same behavior. The young gather in packs under the umbrella of large jellyfish (especially of the Rhizostoma pulmo and Cothylorhiza tuberculata species) finding shelter and protection without any danger as they are immune to the venom of its nematocysts. It gathers in large schools in coastal waters, where it feeds on crustaceans, cephalopods and other fish. It is normally about 30 cm long, but some specimens reach 40 cm. The dorsal fins are gray, the anal fins and whitish ventral fins, the pectoral fins and the ventral grayish-green. The sides are silver and have a black spot on the postero-superior part of the operculum and another on the pectoral axilla. the lateral line is equipped with very wide scutellos. It has an accessory lateral line extended along almost the entire back, which is green with lively iridescence. There are two main populations: the western one that lives off western Europe, and the northern population living in the North Sea. It is found in the north-eastern Atlantic Ocean, from Iceland to Senegal, including the islands of Cape Verde, as well as in the Mediterranean Sea and rarely in the Black Sea. Cassiopeia andromeda collected in autumn 2017, from La Cala marina. Upside-down jellyfish of the genus Cassiopea produce tons of sticky mucus that trap small prey, such as brine shrimp, almost like a spider’s web. It lives in deep areas between 2 m, but it can rarely be found at low depth, especially in sheltered and shady areas. Here we report the biochemical composition and antioxidant activity of jellyfish. Symptoms include mild pain, rash, and swelling.The horse mackerel ( Trachurus trachurus) or suro or “spicaluru” is a seawater fish from the family of Carangidae. This jellyfish can measure a maximum of 30.0 cm wide. As the male produces the sperm and releases them in the water, the female uses its tentacles to bring the sperm to fertilize its eggs. The medusa female produces the eggs and keeps them. When it is in a medusa form, it reproduces sexually. It reproduces by budding when it is in a polyp form. andromeda and algae Reproduction Īs a cnidarian, this jellyfish has an asexual and sexual reproduction. This symbiotic relationship is called mutualism, where both species benefit from their interactions. In exchange, the Cassiopea andromeda mainly offers protection to the shrimp from the environment. It lives in its tentacles and protects it by taking the parasites off. Therefore, the shrimp has a different symbiotic relationship with this jellyfish.

As the zooxanthellae gets food for the Cassiopea andromeda, in response, it gets the sunlight that is necessary for the photosynthetic dinoflagellate algae. The zooxanthellae live in the tissues of the ventral surface of its body and it is the responsible for the color of it. This jellyfish also lives in a symbiotic relationship with photosynthetic dinoflagellate algae, the zooxanthellae, and with shrimps. Cassiopea andromeda is carnivorous and eats small animals from the sea or just pieces of them after it paralyzes its prey with its mucus and nematocysts when they are released.
