Sawfish use sixth sense

SAWFISH use a sixth sense based in their snouts to hunt and dismember prey, new research shows for the first time, according to National Geographic news.

Previously, scientists had suspected that sawfish - large ocean and freshwater fish found throughout the tropics - use their saws to probe sand or mud for prey.

Now, preliminary experiments suggest that the tooth-lined saw is full of pores that can detect movements or electric fields of passing prey.
