    In 2016 scientists in Switzerland examined the effects of cocaine on zebra fish, a type of striped minnow commonly used in scientific experiments. The researchers were surprised to find that most of the cocaine accumulated in the fish’s eyes instead of their brain. Some zebra fish eyes contained concentrations of cocaine that were 1,000 times higher than levels that would be lethal to humans.

    Nature is so fucking cool.
