🐾 Animal Age Translator

Every Creature
Runs on Its
Own Clock.

A hamster's year is your decade. A bowhead whale alive today may have been born before the Civil War. We translate animal ages into human years — with real science, real facts, and no made-up math.

Fascinating Facts

Did You Know?

A few facts that will make you see the animal world differently.

🐋

A bowhead whale discovered in 1999 had a 19th-century harpoon fragment lodged in its neck — meaning it survived an attack around 1890 and kept living for another 130 years.

🐙

The common octopus lives only 1–2 years. In that time, it learns to use tools, solve puzzles, and navigate mazes. It dies at what would be roughly the human equivalent of early childhood.

🐢

Jonathan, a Seychelles giant tortoise living on the island of St Helena, is at least 191 years old. He was fully adult when photographed in 1886. He is almost certainly the oldest living land animal on Earth.

🦈

A Greenland shark caught in the North Atlantic was estimated to be 392 years old — born around 1627, during the reign of King Charles I. It may still be alive today.

🐹

A hamster's heart beats 450 times per minute. A human heart beats about 70. Their entire lifespan of 2–3 years contains roughly the same number of heartbeats as a human life of 80 years.
