The area’s first unagi farm was established in 1891. Today, unagi is one of Hamamatsu’s major exports, famous across Japan for its trusted quality and sweet taste. But it’s more than just an export: Anyone who comes to Hamamatsu will know within minutes of arrival that unagi is this city’s star, a major source of local pride and identity, like crab cakes to Baltimore or lobsters to coastal Maine. The evidence can be found in the snacks on display at department-store kiosks, farmer’s markets, convenience stores, even the gift shop of the local castle: cookies called Unagipie, unagi-flavored soda, unagi-enriched potatoes, fried unagi bones. It seems like every street has its own a certified-local unagi restaurant, many of them more than a century old.
There are well-developed pharyngeal tooth plates, and the pharynx has assumed an important function in the movement of food into the esophagus. It also serves as an effective pump in the virtual absence of suction by the gill covers (opercula) for the passage of the respiratory current. The opercular series is much reduced, although numerous curved branchiostegal rays (internal gill supports) are strongly developed to support the long throat wall. Respiration through the skin is important in Anguilla and probably also in other eels. Evolution, paleontology, and classification Studies of the few known fossil eels and the of adults and larvae suggest that eels arose in the (145.5–65.5 million years ago).

Eyes are usually normal in shape but are occasionally telescopic, and the rostrum (an anterior beaklike projection) may be greatly extended forward from the snout. The viscera are located along the ventral aspect, below the myomeres. There is usually a straight unmodified intestine, and the anal vent is often forward of the tail. In some families the larval gut is swollen or festooned at various points along its length, a modification of unknown significance. A long liver, with a well-defined gallbladder, occurs anteriorly on either side of the intestine.
