📖 How It Works

🧮 Simple Conversion Formula

Otters live about 15 years. Their first year equals roughly 8 human years, and each later year adds about 5 human years, mapping a full otter life onto a human one.

🐾 Based on Average Lifespan

River otters live about 8-12 years and sea otters 15-20, so we map an average 15-year otter life onto a human lifespan of roughly 80 years. Otter pups grow up fast.

📅 Enter Age in Years + Months

Pick the whole years and the extra months from the dropdowns, then hit Calculate. The tool converts the combined age to its human equivalent and tells you the life stage.

💡 Why It Matters

🦦 Understand Otter Families

Otters raise pups, teach them to swim and hunt, and some species live in family groups. Human-age equivalents help researchers explain those bonds.

🏞️ Support Wildlife Rehabilitation

Rehabilitators use age to decide diet, swimming lessons, and release timing for orphaned pups. Human-age equivalents make care plans easier to communicate.

📚 Compare Life in the Wild

From a blind pup to a playful adult, otters pack a lot of life into 15 years. Seeing a 10-year-old otter as a 53-year-old human puts their journey into perspective.
