query: How long do sawfishes get?
passage: Sawfish
Sawfishes, also known as carpenter sharks, are a family of rays characterized by a long, narrow, flattened rostrum, or nose extension, lined with sharp transverse teeth, arranged in a way that resembles a saw. They are among the largest fish with some species reaching lengths of about 7–7.6m (23–25ft).[2] They are found worldwide in tropical and subtropical regions in coastal marine and brackish estuarine waters, as well as freshwater rivers and lakes.[3]
passage: Sawfish
Relatively little is known about the reproductive habits of the sawfish, but all species are ovoviviparous with the adults females giving birth to live young once a year or every second year.[3] In general, males appear to reach sexual maturity at a slightly younger age and smaller size than females.[3] As far as known, sexual maturity is reached at an age of 7–12 years in Pristis and 2–3 years in Anoxypristis. In the smalltooth and green sawfish this equals a total length of 3.7–4.15m (12.1–13.6ft), in the largetooth sawfish at 2.8–3m (9.2–9.8ft), in the dwarf sawfish about 2.55–2.6m (8.4–8.5ft), and in the narrow sawfish at 2–2.25m (6.6–7.4ft).[3] This means that the generation length is about 4.6 years in the narrow sawfish and 14.6–17.2 years in the remaining species.[3]
