Tarantula Age tools: what they help with
These tools turn your tarantula's age into something easier to act on: a human-year equivalent, the life stage it is in now, and a realistic lifespan range. Life stage decides more than people expect. Food, exercise, how often to see the vet and which health checks are worth asking for all shift as a tarantula gets older.
What to know about age and life stage for tarantulas
Tarantulas typically live 10 to 25 years. They reach maturity at about 3 years, and aging slows after that.
