Can Tardigrades die of old age?
Can these little beasties make it to old age? Tardigrades are probably the most paradoxical animals on the planet. … And yet, tardigrades can survive for much longer if they go into a state called cryptobiosis, which is triggered when environmental conditions become unbearable.
What is the most indestructible animal?
TardigradesTardigrades are among the most resilient animals known, with individual species able to survive extreme conditions—such as exposure to extreme temperatures, extreme pressures (both high and low), air deprivation, radiation, dehydration, and starvation—that would quickly kill most other known forms of life.

What makes a Tardigrade indestructible?
They can resist radiation Among the animal’s many coping strategies is a protein that protects its DNA from radiation damage. The researchers named it “Dsup” (short for “damage suppressor”).
