Animals, belonging to the kingdom Animalia, are multicellular eukaryotic organisms that are heterotrophic, meaning they obtain energy by consuming other organisms. They exhibit a wide range of diversity, from simple invertebrates like sponges and jellyfish to complex vertebrates such as mammals and birds.<\/p>\n<p>Classification<br \/>\nAnimals are classified based on shared characteristics, primarily through the system of taxonomy. The major phyla include:<\/p>\n<p>Porifera (Sponges): Simple, porous organisms that filter feed and lack true tissues.<br \/>\nCnidaria (Jellyfish, Corals): Radial symmetry, tentacles with stinging cells, and a simple nerve net.<br \/>\nPlatyhelminthes (Flatworms): Bilateral symmetry, no body cavity, and often parasitic lifestyles.<br \/>\nNematoda (Roundworms): Cylindrical bodies, complete digestive systems, and widespread in soil and hosts.<br \/>\nAnnelida (Segmented Worms): Segmented bodies with bristles, including earthworms and leeches.<br \/>\nArthropoda (Insects, Crustaceans, Arachnids): Exoskeletons, jointed appendages, and the largest phylum by species count.<br \/>\nMollusca (Snails, Octopuses): Soft bodies often protected by shells, with a muscular foot for movement.<br \/>\nEchinodermata (Starfish, Sea Urchins): Radial symmetry as adults, water vascular systems, and marine habitats.<br \/>\nChordata (Vertebrates and Tunicates): Possess a notochord at some stage, with vertebrates (fish, amphibians, reptiles, birds, mammals) having a backbone.<\/p>\n<h3>Table of contents<\/h3>\n<ul class=\"article_list\">\n<li><a href=\"#1\">Part 1: OnlineExamMaker AI quiz generator &#8211; The easiest way to make quizzes online<\/a><\/li>\n<li><a href=\"#2\">Part 2: 20 animal biology quiz questions &#038; answers<\/a><\/li>\n<li><a href=\"#3\">Part 3: OnlineExamMaker AI Question Generator: Generate questions for any topic <\/a><\/li>\n<\/ul>\n<p><img decoding=\"async\" src=\"https:\/\/onlineexammaker.com\/kb\/wp-content\/uploads\/2025\/09\/1955-animal-biology.webp\" alt=\"\"\/><\/p>\n<h3 id=\"1\">Part 1: OnlineExamMaker AI quiz generator &#8211; The easiest way to make quizzes online<\/h3>\n<p>When it comes to ease of creating a animal biology assessment, OnlineExamMaker is one of the best AI-powered quiz making software for your institutions or businesses.
