A giant river otter thought to be locally extinct was recently spotted in Argentina for the first time in over 30 years.
Researchers unexpectedly sighted the otter as it was swimming in El Impenetrable National Park’s Bermejo River. Sebastián Di Martino, the director of conservation at Fundacion Rewilding Argentina, was kayaking down the river when the animal caught him by surprise.
Di Martino recalled the sighting in an email to Gizmodo, saying, “We grabbed the cell phone and started filming it, when he poked his body out of the water and showed the unmistakable white bib, we had no doubts, it was a giant river otter.”
“We could not believe it, the record is incredible and how that specimen got here raises thousands of questions,” said Di Martino. Giant river otters hadn’t been spotted in this particular river in over 100 years.
