A giant river otter has been spotted in the Argentina River after many feared this species had gone into extinction. The otter was spotted beside the canoe in which the director of conservation at Rewilding Argentina, Sebastián Di Martino, was seated.
One would say this is a good omen as this species had not been spotted in the country since the 1980s. For more than a century the otter hasn’t been spotted on the Bermejo River. However, the waterway is linked to the Paraguayan Pantanal, this simply explains that the giant river otters swam there. This would have been a journey of more than 600 miles.
It reared up, so its white chest was visible, which I recognized as the giant river otter. At this point, your legs go weak and your heart starts beating faster.Martino
Di Martino suggests that the otter he spotted was part of a remnant population since otters are always in family groups. He said that this population had been undetected all this while. This could be true since Impenetrable National Park is 500 square miles of rivers within Gran Choco Forest.
Giant river otters are often regarded as “Wolves of the River,” as these species are predators and their hunting behavior indicates a regulatory impact on the rest of the ecosystem, keeping the riverine world in check. Otters are also known to be very curious and charismatic. They can weigh over 60lbs and grow as long as 4.5-feet.
