The term 'long-jawed fish' refers to two species of fish, the Gars (4 letters) and the GAR (3 letters). Gars are a family of primitive ray-finned fish that are native to North America and Central America. They have long, slender bodies and large, toothy jaws. The GAR is a species of fish that is related to the Gars, but is found in Africa, Asia, and Europe. It has a long, slender body and a large, toothy jaw. Both species of fish are known for their long jaws and sharp teeth, which they use to feed on smaller fish and aquatic invertebrates.
