Giant River Otter (Pteronura brasiliensis) - Pantanal, Brazil
Fifteen or twenty minutes after our Jaguar sighting, we came across a group of Giant River Otters at their den. This was the first of two sightings we had of this rare species. Photographs of the second sighting are available here. When we came across them, they had just come out of their den and stepped into the water.
More photographs inside.
