Rare Polymita tree snails living in eastern Cuba are on the verge of extinction because of their beautiful shells. The brightly coloured and decorative shells are popular among collectors, which is drastically reducing their numbers in the wild.
Cuban and British scientists are trying to preserve these snails by breeding them in artificial conditions. The most endangered species — Polymita — has beautiful patterns in light green, blue, and yellow colors.
Experts believe that it is precisely this beauty that puts the snails at risk. Their DNA is being studied to identify the genetic causes of the colouring and to clarify the species.
Although the shell trade is restricted internationally, it still continues freely in some countries. Online, Polymita shells have been seen priced up to 160 pounds sterling(approximately 2.7 million uzbek soums).
Scientists hope to uncover the biological secrets of the snails before they disappear completely.
