Smalltooth sawfish

Smalltooth sawfish are mostly found in coastal marine and estuarine brackish waters. It prefers water less than 8 m (26 ft) deep, but adults are occasionally seen offshore at depths of up to 122 m (400 ft). During periods with increased salinity, juveniles have been seen far up rivers. This species is mostly found in places with soft bottoms such as mud or sand, but may also occur over hard rocky bottoms or at coral reefs. They are often found in areas with mangrove or seagrass. The lower water temperature limit is 16–18 °C (61–64 °F).
