Physically, they are of medium height and robust build, with a height that can vary between 5 and 6 feet and a weight that can even reach a hundredweight or more. They are mammals adapted to aquatic life, with an elongated, irregularly cylindrical body and a thick adipose layer covered by dense, short, velvety and impermeable hair. They have a small and slightly flattened head and ears without an external auricle. Their muzzle has long and thick whiskers, and their feet are wide and flattened, similar in all respects to fins, giving them a characteristic waving and funny walk. Their color can vary from blackish-brown to whitish-grey, sometimes spotted with black on the backside.

Seal people are perhaps the oldest democratic system in history. In fact, they have never had a real king or leader to rule them, and since prehistoric times, they have been based on a highly liberal democracy governed by laws and regulations, far from any concepts of anarchy or monarchy. Each choice and decision are made through a polling station joined by all members of adult age. This system was then also adopted by their neighbors, the Hummingbirds, even before the agreements that made them a single people and a single government on the island. Furthermore, the Seal people have a highly liberal culture that allows anyone to live their life as they please.
Their communities are mainly settled on coasts and cliffs, with large houses sometimes built in stone and clay, and sometimes carved directly into cliffs' rock. In their culture, it doesn't matter whether a single person, a family, or even three or five families live inside the same house, as long as there's space to allow everyone a dignified life and sufficient well-being.

Their economy is obviously based, as their whole lives, on the ocean and its resources. Fishing, both in small rivers and off the ocean, as well as fish farming, are the basis of all their activities. Nonetheless, handcrafted creations and practical activities are also important, from ceramics to carpentry, from metallurgy to agriculture, both on land and in the sea, with regards to vegetables and seaweeds. They have a thriving culture, both literary and scientific, and much of their philosophical thinking is based on the pragmatism of logical-deductive thinking. With the exception of art and fictional literature, everything that is exhibited and commonly accepted must be based on logical and empirically verifiable elements.
