Is fish the only animal in rivers?
NO BEACAUSE SOMETIMES CLAMS ARE.
Life cannot exist without water in some form, and rivers provide an abundant source of water which can be used in many ways. Rivers are important because the water can be used for: * drinking (obviously) * washing * animal life / animal habitats * irrigating crops * transportation * food source (e.g. fish) * sports and recreation
Probably not. First of all, hurricanes can only form over ocean sized bodies of water, not lakes or rivers. It may be possible for ocean fish to be transported to a lake by the storm surge, but they die quickly in the low-salinity water. Tornadoes have been known to pick up fish, and occasionally larger animals, out of lakes and rivers, but they don't survive the trip.
