Freshwater Sharks and Rays

Although most people think of sharks and rays as exclusively saltwater inhabitants, quite a few species actually make use of freshwater living spaces. In a 1995 paper, elasmobranch systematist Leonard Compagno and shark fisheries biologist Sid Cook surveyed the diversity and distribution of freshwater sharks and rays. Compagno and Cook reported that some 43 species of elasmobranch in 10 genera and four families penetrate freshwater environments in Australia, Southeast Asia, western Africa, eastern South America, Central America, and southeastern parts of North America. Coastal elasmobranchs, including some skates (family Rajidae), smooth dogfishes (Triakidae), pajama catsharks (Poroderma spp.), and Sandbar Sharks (Carcharhinus plumbeus) regularly enter estuaries to feed or give birth to young. More impressive yet are stingrays (Dasyatidae, Potamotrygonidae, and others), sawfishes (Pristidae), and the notorious Bull Shark (Carcharhinus leucas), all of which penetrate far up freshwater rivers — the Bull Shark has been recorded some 2,600 miles (4,200 kilometres) from the mouth of the Amazon River — and some even complete their life cycles in freshwater. Yet, in theory, it should be next to impossible for a 'saltier than seawater' elasmobranch to survive in fresh water........
