A tardigrade's trick: dry out and turn to glass.

A tardigrade survives drying out by pulling in its limbs and shrivelling into a ball called a tun, shedding almost all of its body water while its metabolism falls to a near-standstill. Tardigrade-specific proteins appear to set the inside of its cells into a protective glass until water returns.

Step by step

  1. As it dries out, a tardigrade pulls in its legs and shrivels into a ball called a tun.
  2. It sheds almost all its body water; metabolism falls to a near-standstill.
  3. Special proteins appear to set its cell interiors into a protective glass until water returns.
