Saw sharks (9 species) are a very unusual group that is often confused with sawfishes, which are rays. The most obvious difference between the two is that saw sharks possess barbels and the teeth, located on the prolonged snout, are different sizes. Only five species are known. One species, the sixgil sawshark (Pliotrema warrani), possesses 6 gill slits and lives on the south-eastern Cape Coast of South Africa.
Not much is known about the general biology of this order.
