Animal Classification
Animals are classified into groups based on characteristics like body structure and presence of a backbone, helping organise the vast animal
Core concept
Animals are broadly divided into vertebrates (having a backbone) and invertebrates (lacking a backbone), with invertebrates being far more numerous.
How it works
Vertebrates are further classified into fish, amphibians, reptiles, birds, and mammals, each with distinct characteristics and adaptations.
Why it matters
Invertebrates include diverse groups like insects, molluscs, and worms, showing incredible variety in body structure and habitat.
Key detail
This classification system helps scientists study relationships between animals, their evolution, and adaptations to different environments.
