ロンドン動物園
Captive populations have been established at several zoos, including ZSL-London Zoo (UK) (since 2008) and the Steinhart Aquarium of the California Academy of Sciences in San Francisco (USA) (since 2013). The general aim has been to research how to set up a captive assurance colony in event of extinction in the wild. In 2014, breeding was successfully achieved at ZSL-London Zoo.
