Here is the first in a four part series of short videos about the Techno-tortoise™, Hardshell’s 3D printed tortoise model. Tortoises are under assault from ever increasing numbers of ravens. The young reptiles are essentially defenseless for their first 5-7 years. For all that time they must somehow avoid being spotted (and eaten) by the birds. That is becoming increasingly less likely and presents conservationists with a daunting challenge. Part 1 of the series lays out that problem.
