Merpeople

The Merpeople are sentient beings that live underwater, one of their homes being at the center of the lake at Hogwarts. Merpeople have a great love of music. They can breather air for short periods of time, above water their voices sound like screeching, but below water they are understandable but sound croaky. Their language is called Mermish, it is a language the Albus Dumbledore can understand. They can grow gardens of weed, and a few Merpeople keep Grindylows as pets. The Merpeople's village at Hogwarts is lead by Merchieftainess Murcus.
