Pollution is turning sea snakes black. The Turtle-headed Sea Snake (Emydocephalus annulatus) normally has a banded pattern (see above), but individuals found in polluted waters around New Caledonia are increasingly melanistic. It’s a phenomenon called “industrial melanism”: melanin tends to bind to metal ions of trace elements like arsenic and zinc; melanism and an increased shed cycle allows these snakes to rid themselves of toxic metals.

Speaking of sea snakes, say hello to the Yellow Sea Snake (Hydrophis platurus xanthos), a newly discovered subspecies of the Yellow-bellied Sea Snake that is found in the warm, turbulent, anoxic waters of Golfo Dulce, off the Pacific coast of Costa Rica [Zoo Keys]
And what is almost certainly the weirdest reptile story ever to come to my attention: a story about turtle boners. No wait, it’s better than you think! It’s really difficult to figure out a turtle’s sex. So researchers came up with the idea of—oh boy—using a vibrator to stimulate the turtle: male turtles would get an erection. So: turtle boners. In the study, the method had a 100 percent accuracy rate. Because: turtle boners. Science is awesome. That is all. [Acta Herpetologica]
