‘Cocaine King’ Pablo Escobar gives biologists rare chance to study ecological impact of hippos gone rogue

They’re still collecting data at this point and will present findings next June.

I also found it interesting that the researchers noted that the hippos in Columbia were more docile and the Columbians were more at ease being near them because of their more docile behavior. The researchers may extend the work into a comparative study of hippo behavior as a result.
