Most eukaryotes do not have a developed nervous system. In fact, the presence of a complex nervous system is predominantly a characteristic of the animal kingdom within the eukaryotic domain. Organisms like plants, fungi, and most protists, which are also eukaryotes, do not possess a nervous system. Among animals, a well-developed nervous system is especially characteristic of vertebrates and many invertebrates. The complexity of the nervous system can vary significantly; for instance, invertebrates like jellyfish have simple nerve nets, while mammals have highly complex nervous systems with large brains and an extensive network of neurons.
