That would be like asking how to get a elephant not to be so huge or how to make a fish breath air...[/quote] Time for science- Fish do breath water. They use there gills to seperate the oxygen from the water. The oxygen geos through their respiratory system and into there blood stram and is distrubuted to cells.The cells remove what they need from the oxygen and pass it back out through their gills as carbon dioxide. And thats how a fish works. THE END. [/quote] A malnourished elephant would probably also be a bit smaller, but maybe not as signififcantly as selectively bred elephants. Gills are the fish equivalent of lungs-- large surface area, rich blood supply, wet surface.--although fish also use a counter-current exchange system (like ducks have to stop them gertting cold feet when walking on ice) so their lungs are more effective at obtaining oxygen from the water---they need to, as water only has about 5-7% oxygen, as opposed to air which has just over 20% oxygen ---interestingly factoid--ever seen the movie "The abyss"?--that bit at the end where the guy breathes liquid?--humans can actually do that--the main thing that prevents us from doing so is the previously mentioned relative oxygen content of water--animals with lungs can breathe water if it's super saturated with oxygen.--hooray!
