The creatures with the shortest lifespans

In North America, these tiny insects are found near bodies of water. In the water where they are laid, they begin life as eggs, and soon after, they hatch.

Mayfly

For weeks, months, or even years, some mayfly nymphs remain in the water. However, they only survive for less than 24 hours after emerging and molting into adults.

A tiny worm-like creature known as a gastrotrich can be found globally in freshwater environments.

These animals, sometimes known as "hairybellies" or "hairybacks," grow swiftly in the egg stage before emerging into little adult forms of the worm. A quick reproductive cycle is essential for the survival of their species because of their short lifespan.

The accumulated fat from their larval stage is what adult luna moths eat to survive since they lack mouths. They just exist to breed, and then they quickly pass away.

Breeding is crucial to the survival of the species because of this. However, Pennsylvania, where they are usually found, only has two generations of luna moths per year.

Since the Jurassic period, when dinosaurs ruled the Earth, mosquitoes have existed as a species.
