Largetooth Sawfish

Creature Feature – Largetooth Sawfish

Today we take a detailed look at the largetooth sawfish.

Sawfish are easily distinguished by their long, saw-like rostra. While they are often mistaken for sharks they are actually rays. Sawfishes are arguably the most threatened family of marine fishes in the world. The global populations of all five species have experienced historic declines greater than 90%, with the largetooth sawfish not only number 1 on the EDGE Shark list, but also has the highest-ranking score of any EDGE species!
