Let’s find out how long do animals live on an average. Do you have an idea about it, if no, then let me share it with you briefly.

The average lifespan of animals varies greatly depending on the species, size, and environmental factors. Here are some rough average lifespans of different animal groups:

Mammals

Small mammals (e.g., mice, rabbits): 1-5 years
Medium-sized mammals (e.g., cats, dogs): 10-20 years
Large mammals (e.g., horses, cows): 20-30 years
Primates (e.g., monkeys, apes): 20-60 years

Birds

Small birds (e.g., sparrows, finches): 2-5 years
Medium-sized birds (e.g., pigeons, crows): 5-15 years
Large birds (e.g., eagles, owls): 20-50 years

Reptiles

Small reptiles (e.g., lizards, snakes): 5-15 years
Medium-sized reptiles (e.g., turtles, crocodiles): 20-50 years
Large reptiles (e.g., alligators, Komodo dragons): 30-60 years

Fish

Small fish (e.g., guppies, goldfish): 2-5 years
Medium-sized fish (e.g., cichlids, groupers): 5-15 years
Large fish (e.g., sharks, rays): 20-50 years

Insects

Small insects (e.g., flies, bees): several days to several weeks
Medium-sized insects (e.g., butterflies, moths): several weeks to several months
Large insects (e.g., beetles, grasshoppers): several months to several years

Keep in mind that these are general estimates. Individual animals may live longer or shorter lives depending on various factors. These factors include diet, habitat, and disease.
