metazoans

Metazoans are multicellular animals that make up the majority of animal life on Earth. Their bodies are composed of many specialized cells organized into tissues and organs that perform specific functions, such as digestion, movement, and sensory processing. This cellular organization allows them to grow larger and develop complex behaviors compared to single-celled organisms. Examples include insects, mammals, fish, and birds. Metazoans have evolved diverse features to adapt to different environments, making them a wide-ranging and important group within the animal kingdom.
