Mammals - Birds - Reptiles - Amphibians - Fish - Invertebrates

Advanced Categories

This blog began as a result of my interest in why animals develop unique and strange adaptations. An integral part of understanding this is seeing how different groups of animals are related to each other. This is a complete list of animal groups (Vertebrates are grouped by order except fish; there are far too many orders of fish to list here, so I have put them in the common groups of bony, cartilaginous, and jawless. Invertebrates are grouped by phylum.).
