Pablo Escobar's infamous 'cocaine hippo' killed in Colombia car accident.

A hippo descended from Pablo Escobar's private menagerie has died in Colombia after being hit by a car. The hippos were illegally brought into Colombia in the 1980s by Escobar as part of a collection of exotic animals he amassed at his ranch. Since then, they have reproduced rapidly and there are now between 130 and 160 of the hippos, spread far beyond Escobar's former ranch. Recently declared an invasive species in Colombia, the hippos' threat to agriculture and people's safety has been well documented in research, as has the impact of hippo waste on oxygen levels in bodies of water, which can reduce water quality and cause mass fish deaths.
