- Amphibians – This entry explores a group of cold-blooded vertebrates comprising frogs, toads, newts, and salamanders. They are distinguished by their life cycle, typically being postulated in water as fertilized eggs, further developing into larvae that breathe through gills, and eventually transitioning into adults who breathe via lungs or through their skin.
- Birds – An extensive discussion on avian species, characterized by their feathers, beak with no teeth, oviparous hard-shelled eggs, high metabolic rate, and strong yet lightweight skeletons. Articles would cover everything from popular breeds to migratory patterns and bird behaviors.
- Insects – This article considers the largest group of hexapod invertebrates within the arthropod phylum, with a detailed view on insect diversity, life cycle, anatomical structures, behaviors and wide ecological roles they play in the ecosystem.
- Fish – Covers the wide variety of aquatic creatures populating oceans, lakes, and rivers globally. It elaborates on the characteristics of fish, their habitats, various classifications, and relevance to human society.
- Mammals – A comprehensive section that delves into the world of endothermic amniotes distinguished from reptiles and birds by the possession of hair, three middle ear bones, and mammary glands. This category also thoroughly discusses the variety of mammals from land-dwelling creatures to those inhabiting seas.
- Reptiles – This introduces a class of vertebrate animals, including turtles, alligators, snakes, lizards, and related species. It delves into their scaly skin, oviparous/ovoviviparous nature, how they are ectothermic, and their survival strategies.
- Dinosaurs – An exciting section exploring the world of prehistoric, dominant terrestrial vertebrates. It details their evolution, types, extinction theories, and how scientific understanding of them has transformed over the years.
- Endangered Species – A crucial directory detailing animals at risk of extinction, emphasizing the significance of conservation, reasons why species are endangered, and strategies for their protection.
- Aquatic Life – This broad category overviews both saltwater and freshwater organisms. It covers the variety from microscopic life to the blue whale, detailing biodiversity, adaptation methods, categories, and conservation efforts.
- Zoology – Covers the scientific and academic study of animals, providing insights into animal physiology, classification, distribution, habits, and their relation to human beings.
