Hemiramphus
Hemiramphus is a genus of ray-finned fish in the family Hemiramphidae, commonly known as halfbeaks. They are found in tropical and subtropical waters worldwide, typically inhabiting coastal areas, estuaries, and sometimes freshwater. These slender, elongated fish are easily recognizable by their distinctive long, flattened upper jaw, which resembles a beak, while their lower jaw is short and blunt. This unique feature gives them their common name “halfbeak”.
Common Names
Halfbeaks are commonly known as "halfbeaks", "needlefish", or "garfish".
Characteristics
Hemiramphus species are typically small to medium-sized fish, ranging in length from 10 to 60 centimeters. They are characterized by their slender, elongated body, compressed laterally, and covered with small scales. Their dorsal fin is located far back on the body, and their anal fin is positioned opposite it. Their long, flat upper jaw, or rostrum, is used for feeding, allowing them to skim the surface of the water for small crustaceans, insects, and algae.
Environments
Hemiramphus species are generally found in coastal waters, estuaries, and sometimes freshwater. They prefer shallow, calm waters with abundant vegetation. They are often seen schooling near the surface of the water, feeding on plankton and other small organisms.
