Atheris hetfieldi

Atheris hetfieldi, or Hetfield's bush viper, is a species of viper found in Bioko Island. The species gets its name in honour of James A. Hetfield, the vocalist and guitarist from Metallica as the authors were fans of the band from a young age and naming a species after a celebrity helps to raise awareness for biodiversity.
