Exotic turtles have been poached to near-extinction in Asia, but in Hong Kong, these species thrive

• Scientists in Hong Kong are trying to save three species of turtles, CNN reports. 
• The turtles are being hunted for medicinal purposes and to keep as pets.
• Scientists wanted to keep their numbers under wraps but they're now speaking out to spread awareness.

Although bustling metropolitan centers aren't always associated with wildlife conservation — and are sometimes seen as a barrier to it — a team of researchers in Hong Kong say the city is the last hope for certain species of exotic turtles in the region, CNN reports.
