Brief SummaryRead full entry
BiologyThis species often rests on the bottom with the saw held upwards at an angle (6). It feeds on slow-moving fish that form shoals, including mullet, which are tackled by swiping at them with the side of the saw; they may also remove crustaceans and molluscs from the sediment by using the saw to rake them out (4). Like other sharks and rays, fertilisation is internal and females give birth to live young (4). At birth, the saws have a gelatinous coating which protects the mother (3).
