The Arthropods Complex Animals Insects

The video provides an engaging overview of arthropods, a diverse group of invertebrates that have existed for over 541 million years. It explains their common characteristics, such as segmented bodies, exoskeletons, and jointed appendages. The video also classifies arthropods into four main groups: Chelicerata, Myriapoda, Hexapoda, and Crustacea, providing examples for each. Additionally, it highlights interesting facts, such as the vast number of insect species compared to other animals and their bilateral symmetry. The video concludes by emphasizing the long history of arthropods on Earth.
