Most people think of the rays as marine fishes, but there are numerous species, which spend their entire lives in fresh water. Then again other species, for example the mighty swordfish, live in fresh water for at least part of the time and are regularly encountered in the lower courses of rivers. This AQUALOG volume represents the first comprehensive publication in the popular literature to cover all the rays living in fresh and brackish water, with full coverage of: the sawfishes (Pristidae); the guitarfishes (Rhinobatidae); the South American freshwater stingrays (Potamotrygonidae) as well as all the representatives of the electric rays (Torpediniformes), eagle rays, mantas, etc (Myliobatidae), and whiptail stingrays (Dasyatidae) that are known to enter fresh or brackish water. An identification key for all the species is provided. The aquaristically significant freshwater stingrays are depicted in over 400 color photos illustrating a never-before-seen panoply of species and color varieties. All the other species are likewise illustrated as never before. Splendid biotope photos from the natural habitats of these rays round off this superlative volume. This book thus presents an indispensable reference work for anyone interested in rays - aquarists, zoological gardens, scientists, and divers.
