Sawfish

The sawfish is a species of rays that can be found in the tropical and warm temperate waters of the Atlantic, Pacific and Indian Oceans. Its most distinctive feature is its long, narrow nose extension which is lined with sharp transverse teeth that resembles a saw. The saw-like nose is covered with electrosensitive pores that allow the sawfish to detect the movement of prey.
The sawfish is a symbol in many countries. For example, the Aztecs referred to it as an "earth monster", some Asian shamans were using it for exorcism or other ceremonies, it also served as the emblem of the German submarine U-96.
Sadly, the sawfish is listed as "Critically endangered" and risk extinction.
