Vertebrates and Invertebrates Classification

The video tutorial introduces the concept of animal classification, highlighting the vast number of species on Earth and the challenges in cataloging them. It explains the classification system using a toy analogy, detailing taxonomy levels from domain to species. The video distinguishes between vertebrates and invertebrates, discussing their characteristics. It concludes by encouraging viewers to apply classification methods in everyday life, promoting organization and scientific thinking.
