Hippos are thriving in Colombia, more than 30 years after their arrival. In the 1980s notorious Colombian drug lord Pablo Escobar brought the hippos to Colombia for his private ranch. The hippos thrived in an environment similar to their native lands, and today there's a healthy population in the region. But while the hippos are a welcome sight to many, they can also be a nuisance. The massive animals can be seen wandering through city streets and even chasing locals. Cornrare, the Colombian environmental agency that cares for the animals, has recently tried curbing the population through castration.
