You may be wondering, "Where is Palau?" Have you even heard of Palau? It forms the westernmost portion of the Caroline Islands in the western Pacific Ocean.  Well, this tiny island nation's coral reefs are surprisingly good shape say scientists.  The water in the area is more acidic than they thought.  And the reefs seem well equipped to deal with it.

Marine mammals have the peculiar ability to "ignore" a buildup of lactic acid in their muscles.  While human muscles are highly susceptible to it (aka...muscle fatigue) marine mammal muscles are not.

I linked an excellent article from Scientific American to explain how it affects us:
