The population of hippos are doing well in their new home in Colombia, South America, due to the lack of their natural predators including crocodiles, lions, and many others, and the native predators including jaguars, caimans, and other native carnivores are not big enough to hunt these massive animals, as hippos can grow to around 1,500 kg (3,300 lb) and 1,300 kg (2,900 lb) for males and females respectively, very large males can reach 2,000 kg (4,400 lb) and an exceptional male weighing almost 2,700 kg (6,000 lb) has been reported. Male hippos appear to continue growing throughout their lives while females reach maximum weight at around age 25. Because of this, it is expected that the South American hippos will thrive and easily adapt in the world without humans.

The descendants of Escobar's hippos have multiplied from just 40 hippos to more than 2 million hippos, also spreading into Brazil, Argentina, and other South American countries, making South America containing the largest population of hippos on earth. Because of the lack of its natural predators, the hippos of South America are no longer aggressive, since lions, crocodiles, hyenas, and other African predators aren't present in South America, so the South American hippos are now almost completely peaceful herbivores. The hippos are now the largest animals and the top herbivores of South America.
