As reported by the New Straits Times, Malaysia is facing a problem following repeated releases of non-native animals. Both the North American bullfrog (Rana catesbeiana) and the Taiwanese edible frog (Hoplobatrachus chinensis) are raised in Malaysia for food. Unfortunately some well-meaning people have been "rescuing" the frogs from their likely dinner plate destination, by releasing them into local natural areas. Ironically, the last big batch of Taiwanese edible frogs to be found in a botanical garden were recaptured and sent off to a Chinese restaurant.
Bonus points to the New Straits Times for using the frogs' scientific names. But -1 for misspelling Hoplobatrachus. And +1 to Google for recognizing the misspelling :-).
