How urban seasnakes lost their stripes
Researchers studying turtle-headed seasnakes living on coral reefs in the Indo-Pacific noticed something unusual about the snakes' color patterns: seasnakes living in more pristine parts of the reef were decorated with black-and-white bands or blotches. Those in places with more human activity -- near the city or military activity -- were black. As reported in Current Biology on Aug. 10, those color differences are explained by differences in the snakes' exposure to pollution. (2017-08-10)
