The tremendous Amazon River flood has brought amazing benefits to great variety of wildlife. From fish, birds and insects. Mammals are not outside the list: The rare (even rarer than Jaguars) Giant Oters have been observed in Maica Lake, a flodplain area east of Santarem. Fishermen are not quite happy with and put them in danger of being killed. Very few people had the privilege of comtemplating it. My friend Alan Dean Foster went to the limit. Giant Otters are his favourite mammals(amongst many) and he did not miss the opportunity to swim with this juvenile when we were exploring Brazil wildlife some years ago.
