It’s green and it has a saw on its face. These names don’t leave much to the imagination do they? If there is anything though, it would be the size. Not really a fish at all but rather a ray, they can grow to be nearly 7 meters long.

The green sawfish is the largest of all existing sawfishes, reaching up to 7.3 meters in length and its teethed rostra accounts for almost one third of that length!
Also known around the world as the longcomb, narrowsnout, or olive sawfish, this species shows a distinct greenish-brown coloration on the dorsal side of its body. The green sawfish is the largest of the sawfish species and can live for up to 50 years!
This species lives in shallow coastal waters, but has also been encountered in water as deep as 70m. They feed primarily on fish and prawns and reproduce via * aplacental viviparity, in which there is no placental connection and the young are supplied with nutrients from yolk before being born as live young. Litter size is 12 pups.
* Ovoviviparity (aplacental viviparity) is a mode of reproduction in sharks (and other animals) in which embryos develop inside eggs that are retained within the mother's body until they are ready to hatch.
