A giant river otter, previously thought extinct, has been found in Argentina. 

The giant otter was last spotted in the 1980’s, with fears habitat loss and hunting had led to the species extinction in the region.

The return of the otters is being attributed to the formation of the Impenetrable national park in 2014, which aimed to restore natural areas in Argentina.

Giant otters are top predators, and are vital in helping to balance local ecosystems.
