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. [3] Scyphozoans have existed from the earliest Cambrian to the ...
The medusa of the white cross jellyfish is clear ranging from 3 to 5 cm (1.2 to 2.0 in) thick and 10 to 20 cm (3.9 to 7.9 in) wide. [1] Visually it is very similar to Mitrocoma cellularia, but they tend to only grow up to 10 cm (3.9 in) in diameter. [2]
Poralia is a genus of jellyfish in the family Ulmaridae. It is a monotypic genus containing a single species, Poralia rufescens. [1] This jellyfish is pelagic, and is found in deep water in most of the world's oceans. In 2021, a NOAA expedition discovered a possible additional Poralia species in the Atlantic Ocean. [2]
Cubozoa is a group commonly known as box jellyfish, that occur in tropical and warm temperate seas. They have cube-shaped, transparent medusae and are heavily-armed with venomous nematocysts. Cubozoans have planula larvae, which settle and develop into sessile polyps, which subsequently metamorphose into sexual medusae, [ 11 ] the oral end of ...
The medusae of most species are fast-growing, and mature within a few months then die soon after breeding, but the polyp stage, attached to the seabed, may be much more long-lived. Jellyfish have been in existence for at least 500 million years, [1] and possibly 700 million years or more, making them the oldest multi-organ animal group. [2]
Cassiopea ornata are one of many Cnidarian species called the upside-down jellyfish. [1] [2] [3] This pelagic jellyfish primarily lives in tropical waters, off the coast of Australia in shallow lagoons and around mangrove trees. The name "upside-down jellyfish" comes from the fact that it appears to be upside-down in its natural state—resting ...

Drymonema dalmatinum is a large species, growing up to 75 centimetres (30 in) long and weighing up to 25 kilograms (55 lb). The oral arms are very large, making up around fifty percent of the jellyfish's weight. [4]
