Characteristics and Examples Scyphozoans are characterized by their complex life cycle involving a dominant medusa, a scalloped bell margin, and four gonads located in the gastrovascular cavity. Unlike the drifting Scyphozoa, cubozoans are active swimmers, capable of rapid directional changes and surprisingly complex behaviors.

Their potent neurotoxins target the heart and nervous system, making them a significant hazard in tropical waters where they are prevalent. Class Scyphozoa: The True Jellyfish Class Scyphozoa is what most people envision when they think of a jellyfish: large, often colorful, and possessing a prominent medusa stage.
Many hydrozoans exist primarily as colonies, such as the Portuguese Man o' War, which is actually a siphonophore, not a true jellyfish. For jellyfish, which belong to the phylum Cnidaria, class designation typically hinges on the balance between the medusa (bell) and polyp (polyp) stages of their life cycle, as well as the structure of their cnidocytes.

Class Cubozoa: The Box Jellies Class Cubozoa distinguishes itself through a unique cubic or box-shaped bell, a structure that gives these animals their common name. Familiar genera include Aurelia (Moon Jellyfish) and Cyanea (Lion's Mane Jellyfish), the latter of which is one of the largest known species.
