why dont sea mamals need to decompres?
so... whales breath air right? the same air we breath out of out tanks....
if we go too deep... we get stoned... whales go much deeper than humans... and for hours.. they never get bent? why is that?

Don't think whales etc are breathing compressed air -
Pretty much along the same lines as a free-diver- They take a big breath, then dive--

Well, really it is and isn't because it's compressed. The thing is, you body can hold a certain amount of nitrogen in solution. It's only when you introduce more there is a problem, and since they are doing a single breath, they do not get in more nitrogen. That is one of the reasons you should never offer your octo to a passing whale.... er... just one of the reasons.

Actually there is some research going on into cetaceans and some form of DCS. I'm not sure of the credibility of this or how it could be possible, but here it is:
