Tardigrade Larva (Water Bear)

The baby version of Earth's most indestructible animal/Microscopic Life

Tardigrade larvae are even tinier than their famously tough adult forms. Born with the same eight legs and chubby body plan, they immediately possess the survival abilities that make tardigrades legendary: they can survive extreme temperatures, radiation, the vacuum of space, and pressures that would crush a submarine. A tardigrade larva is essentially a microscopic tank wrapped in a cute bear suit.
