What did cnidarians invent?
Cnidarians, such as jellyfish, corals, and sea anemones, are credited with the evolution of the first specialized cells for capturing prey, known as cnidocytes. These cells contain structures called nematocysts, which can inject toxins into predators or prey. This innovation allowed cnidarians to become effective predators in aquatic environments and significantly contributed to the complexity of marine ecosystems. Additionally, their body plan, featuring radial symmetry, has influenced the evolution of numerous other animal groups.
What groups of animals have radial symetry?
Echinoderms (ex: starfish), cnidarians (ex: jellyfish) and and some vermiforms have longitudinal radial symmetry.
What is the family for cnidarians?
The cnidarians are in the Kindom family
Do cnidarians have nerves?
