The jellyfish surround themselves with a layer of mucus containing cassiosomes, independent bodies consisting of a layer of stinging cells surrounding a piece of jelly as described in a 2020 study featuring notable scientists such as Jennie Janssen. Between sixty and a hundred cilia enable the cassiophore to swim independently of the jellyfish ...
The Scyphozoa are an exclusively marine class of the phylum Cnidaria, [2] referred to as the true jellyfish (or "true jellies"). The class name Scyphozoa comes from the Greek word skyphos ( σκύφος ), denoting a kind of drinking cup and alluding to the cup shape of the organism.
Aequorea vitrina, commonly called the crystal jellyfish, crystal jelly, lampshade or disk jellyfish, [2] is a species of hydrozoan in the family Aequoreidae. [ 3 ] [ 4 ] The specific name vitrina means " glassy ", due to its transparent appearance; it should not be confused with Aequorea victoria , which is also sometimes called the crystal jelly.
Scyphozoa is the group commonly known as "true jellyfish" and occur in tropical, temperate and polar seas worldwide. Scyphozoans generally have planula larvae that develop into sessile polyps. These reproduce asexually, producing similar polyps by budding, and then either transform into medusae, or repeatedly bud medusae from their upper ...
Chrysaora fuscescens, the Pacific sea nettle or West Coast sea nettle, is a widespread planktonic scyphozoan cnidarian—or medusa, "jellyfish" or "jelly"—that lives in the northeastern Pacific Ocean, in temperate to cooler waters off of British Columbia and the West Coast of the United States, ranging south to Mexico.
Jellyfish are slow swimmers, and most species form part of the plankton. Traditionally jellyfish have been viewed as trophic dead ends, minor players in the marine food web, gelatinous organisms with a body plan largely based on water that offers little nutritional value or interest for other organisms apart from a few specialised predators such as the ocean sunfish and the leatherback sea turtle.
The benthic comb jelly is a gelatinous organism 5–8 cm wide and 10–20 cm long. It can attach itself to the sea floor using two long filaments and has two retractable tentacles at the opposite end. Its appearance has been said to resemble a two-tailed box kite. [2]
Rhopilema esculentum, the flame jellyfish, is a species of jellyfish native to the warm temperate waters of the Pacific Ocean.It is a popular seafood in southeastern Asia. . In the 1980s, research was undertaken in China into its aquaculture, and it is now bred in ponds in that country before being released into the sea to grow to a mature size suitable for the fishe
