Convert dolphin years to human years. Find out how old your dolphin is in human years and which life stage it has reached.
Dolphins age differently than humans. Bottlenose dolphins typically live around 45 years in the wild, with some reaching 50 or more. To estimate a dolphin's age in human terms, multiply its age in years by about 2.2 — so a 10-year-old dolphin is roughly equivalent to a 22-year-old human.
Just enter your dolphin's age in years and months, and our calculator will show the human-equivalent age, the percentage of a typical 45-year lifespan reached, and the life stage your dolphin is currently in.
Learn how dolphin development compares to human development and why marine mammals grow and mature at their own pace.
Understanding dolphin lifespans and life stages highlights how important it is to protect ocean habitats and marine wildlife.
A playful way to teach kids and adults about marine biology, age comparison, and the amazing lives of dolphins.
