In 1955, Hawaii introduced the rosy wolfsnail to control giant African snails; it instead devastated native tree snails, and 69 years later a species extinct in the wild since 1991 was reintroduced

• The reintroduction is only one part of the recovery strategy.
• Bishop Museum and Honolulu Zoo are also establishing captive snail laboratories, where Achatinella fuscobasis will be reared and made accessible to the public.
• For more than three decades, the tiny Achatinella fuscobasis (snail) existed only under human care.
