Merfolk

Mermaids typically resemble humanoids for the most part, however they have fish-like traits and typically tend to have uniquely colored skin, and they're capable of turning their lower body half into a fish tail in the water. They typically come in as varied in colors as there are for fish.

They're amphibious creatures who can survive in both land and water, however they do not require air to survive. They're capable of swimming at extreme speed, turning their legs into a mermaid tail, breathing underwater through gills.

Mermaids typically lay eggs

Surprise surprise, Mermaids live in the water, typically oceans.

They typicaally feed on smaller fish, along with enjoying various sea plants.

They're typically found in saltwater locations

They have a rivalry with Sirens, who people often mistake them for, as the two usually conflict with one another.

There is a grotto of mermaids along the South coast.

They typically don't have a dress code, usually decorating their body with various sea shells and kelp and waterproof attire. They typically wear kilts and skirts in the place of pants in order to freely swap between their fish tailed forms, and don't usually wear shoes, at most they typically wear sandals.

What makes the difference between a Siren and a Mermaid? Originally, there were only sirens, who tempted prey to the oceans to drown, but some fell for the more humanoid races, finding personal relationships with them. Their children were ostracized by the Siren kingdoms, finding them docile and out of touch with the heart of the sea's true wild and free heart.   These children were the birth of the merfolk, who slowly banded together. Their new form of blood, looking far more humanoid than their siren brethren and far less natural, were looked down upon for their disconnection with the sea, and were presumed to be differentiated from their aquatic deity, Abynyx.   Whilst there were some that chose to live on the land, most refused to leave their ocean homes, and would claim their own underwater kingdoms, albeit smaller than the Sirens, and lacking their siren songs, they had the power to move across the land, not to mention their ties to other races of the land.

They have a burning hatred between the major Siren kingdoms. However they have a close relationship with the humanoid races along the shoreline.
