African Crocodile

Caption

This crocodile inhabits waters around Flag Boshielo Dam, a reservoir on the Oliphants River, just upstream from South Africa's Kruger National Park. Researchers from the Hollings Marine Laboratory reported at least four types of perfluorinated alkyl acids in plasma samples drawn from 45 crocodiles at five sites in and around the park. The highest levels were found in animals living in the reservoir.
