Ottermaaner are playful, nimble Merfolk that stay close to riverbanks.

Ottermaaner are an interesting type of mermaid found in The Netherlands. They are called ottermaaner, meaning otter-men and are technically also classified as a type of elf. They shapeshift into otters using magical otter-skins. Some say the Ottermaaner travel in bubbles, bobbing to and fro above the water. They are most commonly seen inhabiting the River Elbe.
