Sawfish
Sawfish are primarily found in coastal marine and estuarine brackish waters, but they are euryhaline (can adapt to various salinities) and also found in freshwater. The largetooth sawfish, alternatively called the freshwater sawfish, has the greatest affinity for freshwater. For example, it has been reported as far as up the Amazon River and in Lake Nicaragua, and its young spend the first years of their life in freshwater. In contrast, the smalltooth, green and dwarf sawfish typically avoid pure freshwater, but may occasionally move far up rivers, especially during periods when there is an increased salinity. There are reports of narrow sawfish seen far upriver, but these need confirmation and may involve misidentifications of other species of sawfish.
Sailfin flyingfish
The sailfin flyingfish ("Parexocoetus brachypterus") is a member of the flying fish family. Like other members its family, "P. brachypterus" is known for its ability to leap out of the water and glide above its surface. Its distribution range encompasses the Atlantic, Indian, and Pacific Oceans. It is an epipelagic fish and can be found in coastal waters but is rarely encountered in open oceans. They are known to spawn during September to April in the waters near Barbados and Puerto Rico. Appearance wise, the sailfin flyingfish is known to have a robust build, blunt snout, short pectoral fins and having a long dorsal fin.
