Not all mermaids are girls with flowing hair and a fish tail. Some are half seals, dolphins, and even octopuses. Some of them also have membranes between the fingers or red eyes.

Sometimes they cause storms, sink ships and kidnap sailors, but they also often save shipwrecked people, warn against bad weather and fulfill wishes. And sometimes they go ashore, assume human form and marry mortals. But they always miss the sea ... and eventually return to it.

Open this book and discover the wizarding creatures hiding among the waves: mermaids and water maids ... and bearded, green-haired mermaids!
