Tardigrade in its active state

A scanning electron microscope image of a tardigrade in its hydrated, active state.

This scanning electron microscope image shows a tardigrade in its hydrated, active state. Tardigrades have five body sections encased in a sturdy but flexible cuticle. When the tardigrade is in an inactive tun state, it resembles a small oval ball.
