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. They are carnivorous predators, using their tentacles armed with nematocysts to capture plankton, small fish, and other gelatinous zooplankton.
Dangerous Jellyfish Classes You Should Know About
Cubozoans have separate sexes, with a complex lifecycle that includes a sedentary polyp phase. 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.
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. They possess advanced eyes clustered around the bell, allowing them to form crude images of their surroundings, a feature largely absent in their scyphozoan cousins.
Dangerous Jellyfish Classes to Watch For
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. Many hydrozoans exist primarily as colonies, such as the Portuguese Man o' War, which is actually a siphonophore, not a true jellyfish.
