Needle-nosed fishes are a group of fish that have long, slender snouts. Gars (4 letters) are a type of needle-nosed fish that are found in freshwater habitats in North and Central America. They have an elongated body and a long, narrow snout with sharp teeth. Gars are predatory fish that feed on other fish, crustaceans, and insects. They are also known for their hard scales, which provide them with protection from predators.
