We flew from Tarapoto to Iquitos and hired there a guide with boat. We went 200 km upstream and found there at different locations the D. reticulatus (the normal one and the striped one), D. duellmani, D. ventrimaculatus and E. hahneli. We also saw several kinds of lizards, snakes, monkeys, sloth’s, parrots and lots of other birds and the pink and grey dolphin.
