Two baby Egyptian tortoises which have hatched at Chester Zoo may be crucial in saving the species from extinction.
Curators at the zoo say the creatures are smaller than a 50 pence piece and weigh less than a strawberry.
Kevin Buley, organiser of international tortoise and turtle conservation campaign Shellshock, said the species is critically endangered in the wild.
The babies hatched within days of each other and are being kept in a private conservation and research unit.
