Once widespread in U.S. waters, this fish with the toothy, saw-like snout has been an icon for some Gulf communities. Now the stuffed sawfish that hang in some backcountry saloons and fisherman's pubs may become a reminder of the past.

Two species of sawfish that inhabit the Gulf, the smalltooth and largetooth, are greatly threatened by encroaching oil. The largetooth sawfish may already be extinct in the region, and many of the smalltooth populations have nurseries that are confined to a region now threatened by the oil spill.
