Durrell Wildlife Trust has launched an emergency appeal to try and save the Ploughshare Tortoise.
It is estimated that there are fewer than 100 in their native homeland of Madagascar.
The trust estimate the species, which is one of the most endangered reptiles in the world, could be extinct in two years.
They want to raise £1,000 to protect their breeding facility in Ampijoroa, Madagascar, which has been targeted by poachers.
The money raised will be used for solar panels and batteries to power alarms and security cameras, which help the facility's guards.
