Giant River Otter Mom with Pup, BrazilI’ve seen and photographed giant river otters in a few countries in South America, but I definitely had my best opportunities in Brazil. This image of a mother with her pup (and an unfortunate fish) was taken in Brazil’s Pantanal region. Nikon D300 with Nikkor 200-400mm lens (at 270mm) ISO 800, f/4 at 1320th of a second.
