Some cicadas can live up to 17 years underground without eating or drinking.
Some cicadas, specifically the Magicicada septendecim, have a unique life cycle that involves spending 17 years in a state of dormancy underground, where they don't eat or drink. During this time, they rely on stored energy reserves from their juvenile stage. This remarkable adaptation allows them to synchronize their emergence with specific years, creating massive swarms that can be heard for miles. Scientists have studied these cicadas in detail, providing evidence for their extraordinary behavior.
