See also: List of fishes in the Magdalena riverThe Magdalena River crosses a wide variety of ecosystems, like páramo in its headwaters, dry forest in the upper part of its valley, rain forest in its middle course, and swamps and wetlands in its lower course. The Spectacled Caiman, iguana, pelican and catfish are abundant in these ecosystems but other animal species like the Prochilodus magdalenae, crocodile and red-footed tortoise are in critical danger of extinction. In addition, there is a possible risk posed by invasive hippopotamus. Originally imported by Pablo Escobar, these hippopotami became feral following his demise, and have since expanded beyond their original home on Hacienda Napoles into nearby regions of the Magdalena River.
