Some useful information on needlefish:


  • These marine fish look just like the North American freshwater gars, with long jaws and sharp teeth.


  • They tend to be 1.2 inches to 37 inches long, with a dorsal fin, but the unique feature of the Needlefish is their beak. The beak is long and narrow with many sharp teeth inside it.


  • Young needlefish do not have a fully developed upper jaw; this means they only eat plankton. Once the upper jaw is developed, they now eat other types of fish.


  • Needlefish mainly eat other (smaller) fish. Fresh water species of needlefish are eating other fish too.
