14. Three-Part Bodies
All insects share a distinctive three-part body: the head, thorax, and abdomen.
The head houses sensory organs and mouthparts; the thorax anchors the six legs and wings; and the abdomen contains digestive and reproductive organs.
This clear segmentation sets insects apart from other animals, such as worms or spiders, whose bodies are organized differently.
This efficient design supports their versatility and success in countless environments.
