This group includes diverse phyla such as Arthropoda (insects, spiders, crabs), Mollusca (snails, octopuses), and Cnidaria (jellyfish, corals). Arthropods are the most successful, representing the largest percentage of all known animal life.
At some point in their life cycle, almost all animals are capable of independent movement. Classification and Diversity Animal Kingdom
Unlike bacteria or protists, animals are composed of many cells that work together in specialized tissues and organs. This group includes diverse phyla such as Arthropoda
Taxonomists divide the kingdom into approximately 35 phyla based on body symmetry, tissue layers, and developmental patterns. The most significant divide is between (those without a backbone) and vertebrates (those with a backbone). and Cnidaria (jellyfish
Despite their vast differences, all members of the Animal Kingdom share several core traits:
