The Giant River Otter or ‘water dog’ is the most endangered neotropical animal. Growing up to 6 feet long (hence its name), this incredible mammal was hunted for its fur. Today Giant River Otters are protected and it is illegal to trap them for the pet trade or for their pelt and they can be commonly seen in the rivers and lakes in Guyana. Diane McTurk is world renowned for her work rehabilitating Giant River Otters at Karanambu in the North Rupununi.
