There are a total of 1,202 Animals that have been compiled and organized in this comprehensive list. The selection includes widely recognized common names matched with accepted scientific names, concise habitats, and species of ecological or conservation relevance.
Animals are multicellular, eukaryotic organisms that obtain energy by consuming organic matter. They range from microscopic invertebrates to the blue whale, spanning vast sizes and life strategies. Animals drive ecosystems, pollinate crops, provide food and materials, and inform medicine and conservation practice.
Interesting and little-known facts about Animals:
– Scientists have described about 1,500,000 animal species; estimates suggest 7–8 million may exist worldwide.
– The blue whale is the largest animal, reaching over 30 meters and weighing up to 200,000 kg.
– The smallest known vertebrate is a frog, Paedophryne amauensis, at about 7.7 millimeters long.
– About 28% of assessed animal species face elevated extinction risk, based on IUCN Red List assessments.
– Animals inhabit every biome, from the Mariana Trench at roughly 11,000 meters depth to mountain summits above 8,000 meters.
– Reproductive strategies vary widely: some species use parthenogenesis, and others change sex during their lifetimes.
The alphabetical index leads to lists organized by initial letter. Each list includes these data columns: Common name; Scientific name (accepted); Conservation status (IUCN where available); Habitat (biome + region); Short description (20–40 words); Internal link and CSV export.
