Animal Fact Charts
One statistic at a time, for every animal in the database. Each chart is sortable and links through to the full animal profile.
Animal Lifespans: How Long Animals Live
How long an animal lives depends on its size, its metabolism, its environment and how many things are trying to eat it.
Animal Weights: How Much Animals Weigh
Animal weights span more than eleven orders of magnitude, from insects weighing a few milligrams to the blue whale at well over 100 tonnes.
Animal Sizes: Height and Length
Size is measured differently for different body plans.
Animal Speeds: How Fast Animals Run, Swim and Fly
Top speeds are among the least reliable animal statistics, because they are rarely measured under controlled conditions and the most quotable number tends to get repeated.
Animal Gestation and Incubation Periods
Gestation is the time between conception and birth in animals that bear live young.
Animal Diets: What Animals Eat
Animals are grouped by what they mainly eat.
Animal Conservation Status (IUCN Red List)
The IUCN Red List of Threatened Species sorts species by extinction risk into Least Concern, Near Threatened, Vulnerable, Endangered, Critically Endangered, Extinct in the Wild and Extinct, with Data Deficient for species too poorly known to assess.
