Seafolk is the term used to describe the four kinds of water-dwelling folk of Maeovis.
Merfolk are the showiest of the seafolk and live in the largest groups, which are divided into "Kingdoms". They have long, colorful tails that end in fins with swallowtail-like tips. Their hair is brightly colored and their skin takes the same markings as their tails. There are two kinds: Kessixian and Tekeburian. Kessixian coast merfolk have many more bluish-green colors and have vibrant yellow markings. They blend in well with the plentiful seaweed forests around the coast, as well as the coral that takes yellowish hues. Many of them are more adept at marsh and swamp swimming, and have adaptations for freshwater due to the jungle swamps. Tekeburian merfolk are more purple-red in color and have brilliant orange and yellow markings. They blend in with the corals and underwater plants in their region, and they have showier colors for driving away predators.
Merrows are dull compared to their ocean relatives, and only live in two places: The Iksandi Sea and Siana. Biologically, they are very similar to merfolk, though with shorter tails and lacking the extra fin-tips of their oceanic cousins. Iksandi sea merrows frequent the Azohican coast. They are incredibly good at camoflage, blending in to the coastal swamp with their dark green tails and green-tinged hair. The Sianic merrows are lean and have brownish-green or dark yellow tails, with large eyes since they often live in the deep lakes of their region.
Sirens are quick and efficient hunters, traveling the open oceans in packs that can range from small bands of 10-15, like in the north, to massive groups of over 100, like the southern lineage prefer. They are greyish in color with lean builds and sharp fangs and claws. Their tails are often compared to dolphins or sharks, with smooth skin and flukes similar to an orca. The Northern sirens are larger and have broader flukes, while southern sirens are lean and have triangular flukes and an extra set of pelvic fins for more navigation.
Selkies are large and adapted for life in the water.
