Physically, they've a serpentine body without legs, with an average height/length of about 5 feet and a weight usually not exceeding 40-50 kg. They have a long dorsal fin of modest height, elongated until it joins the caudal fins. The color of each speciment varies from silver to black and is often sprinkled with yellowish horizontal stripes or spots of extremely variable shape, number, and size. Despite their unique physical form, they are still able to move slowly on land, because their skin can be temporarily covered with a mucus used for skin breathing, which allows them to live out of water for three or four days. However, they've a constant need to bathe their bodies in saltwater at least once a day. Their fries are born ovoviviparous, meaning they hatch within the mother's body, and families typically have even ten fries throughout their lives.

The Eel people have a long tradition of elective thalassocracy, with rulers succeeding each other through continuous popular consent expressed through oligarchic elections. Despite their primarily artistic and commercial nature, they are also a fighting people, feared and respected. For this reason, they were often targeted by the Boar people and kept busy for many decades in continuous clashes. The Eel people have always been a society of traders and craftsmen, involved in maritime routes with detailed organization and fine skill. Spices and incense, cotton cultivation, extraction of precious metals, and the artistic production of ceramics, paintings, and jewelry are all of great importance in their culture and trade, along with sailing skills. According to popular opinion, it seems that the first contacts between northern continents were due to the Eel people. In fact, given their wide sailing areas, the Eel people have traveled the entire Medisol Sea since ancient times, and their trade routes have put many continents in communication.

Most of their settlements are located around their archipelago's islands, with dwellings and palaces carved into the high cliff rocks. Generally, the homes of the richest are located near or below the water, while the less well-off's homes are located higher up towards the top of the cliffs and mainland interior. Temples, commercial premises, community buildings, and agricultural activities are also located there.

They speak the Itthen language, common to all Anthro fish races, a guttural language accompanied by strong facial expressions, understandable even underwater where sounds are less easy to hear (perhaps a Japanese gibberish).

Religiously they are mostly devoted to Ekoari (deity of science and commerce), Sia Mori (deity of arts and dreams), and Teeje (deity of piracy and navigation), but here and there also thrive the cults of Kudan (deity of poisons and tortures), Caamiran (deity of justice and cities), Jimbasi (deity of honor and courage), and Azlean (deity of medicine and gardens).

Their Ancestral Princes were Kadmòs and Cibele, who taught their race the importance of discretion. They believe that interactions with other races are only necessary in case of need. Trade is important for showcasing their great works and artistic abilities, but this does not mean they must personally interact with customers or establish personal relationships outside of business.

Typical of Eel people is the use a strange type of boat called a skàfos, which is built with a long bow and rounded stern. The design of the boat allows for high speeds and the sails are placed laterally for the sea currents rather than above the hull for wind.
