There's a species of cicada that lives for 17 years underground before emerging to sing - Apparently.
The Magicicada septendecim cicada spends 17 years in a state of dormancy, often referred to as "diapause," before emerging in synchronized broods of millions. This unique life cycle is thought to be an adaptation to avoid predators and ensure the species' survival. Scientists have been able to verify the life cycle by tracking the emergence patterns and genetic analysis of the cicadas, confirming the 17-year cycle.
