The first picture -- the silver fish with the unequal jaws -- is commonly called a garfish in the Eastern Hemisphere. It is one of several generically-described "needlefish", "stickfish", or "aha". Needlefish species are found in freshwater and saltwater.

It is unlike our much chunkier Western Hemisphere freshwater and brackish-water mottled/spotted garfish.

A houndfish is a silver, saltwater, large needlefish with a green back, and whose jaws are equal in length.
