Giant River Otter, Pantanal, BrazilThe giant river otter, or simply giant otter, is the largest member of the weasel family (also known as mustelids). They can grow to six feet in length and are very imposing creatures when seen out of the water like this, resting on a riverbank. This shot also shows off the characteristic white patch on the chest of the giant otter. Photo taken from a boat while searching for jaguars in the Pantanal of Brazil.
