Fresh Water Skin Disease

	Fresh Water Skin Disease Fresh water skin disease (FWSD) is a disease of marine cetaceans in coastal and estuarine environments, caused when they are exposed for extended periods to water with lower than normal levels of salt (hypo-saline). It has been observed in dolphins that were displaced into freshwater lakes, and in normally-salty lakes and estuaries where salinity has dropped suddenly due to flooding or storm runoff. The symptoms are widespread skin lesions and ulcers. Circular lesions can resemble cetacean pox, which is more common in juveniles. Chronic lesions may have overgrowths of algal and/or fungal mats. Extended exposure can lead to over-hydration, electrolyte imbalance, and organ failure. The syndrome has been observed particularly with bottlenose dolphins ''Tursiops truncatus'' in Lake Pontchartrain, Louisiana from 2007, thought to have been trapped by Hurricane Katrina in 2005; with '' T. australis'' at Gippsland Lakes in 2007; with '' T. aduncus'' at the Swan Canning Riverpark (Sw ...

picture info	Cetacean Cetacea (; , ) is an infraorder of aquatic mammals that includes whales, dolphins, and porpoises. Key characteristics are their fully aquatic lifestyle, streamlined body shape, often large size and exclusively carnivorous diet. They propel themselves through the water with powerful up-and-down movement of their tail which ends in a paddle-like fluke, using their flipper-shaped forelimbs to maneuver. While the majority of cetaceans live in marine environments, a small number exclusively reside in brackish water or fresh water. Having a cosmopolitan distribution, they can be found in some rivers and all of Earth's oceans, and many species inhabit vast ranges where they migrate with the changing of the seasons. Cetaceans are famous for their high intelligence and complex social behaviour as well as for the enormous size of some of the group's members, such as the blue whale which reaches a maximum confirmed length of 29.9 meters (98 feet) and a weight of 173 tonnes (190 short tons ...
