Sawsharks are easily confused with sawfish, which also have an elongated snout with teeth-like spikes and a similar body shape.
There are two obvious differences: first are the tendrils on the snout of sawsharks which are missing on sawfish; secondly sawsharks have gills on the sides of their heads like most sharks, while the sawfish, being types of rays, have their gills underneath their heads.
The sawsharks’ tendrils, which are found about halfway along the length of their snout or ‘saw’, are used to dislodge hidden prey in sandy or silty areas or to slash at passing fish.

The electric rays (Torpediniformes) have evolved powerful electrogenic organs that enable them to stun prey.
