Swedish zoologist Georg Dahl worked for many years in one of the little-explored corners of the globe - Colombia. Traveling from the shores of the Atlantic Ocean to the edge of riddles - the upper reaches of the Orinoco River, he fought with stingrays and crocodiles, lizards and anacondas. He met unknown to science fish, turtles, which were described in Indian legends as unknown monsters... The book is filled with the author's love for this region, permeated with humor. She puts Dahl on a par with the best travel writers.
