The Mermaid

A human upper body and a fish’s tail make the familiar mermaid of sea tales. But water beings from different traditions do not all look alike or share one history.

A closer look at the story

Mermaids appeared as carved figureheads on ships. In Denmark, Hans Christian Andersen published The Little Mermaid in 1837. That written fairy tale is one particular story, not the origin of every mermaid tradition.

Dates to put in your notebook

  1. 1837Hans Christian Andersen’s The Little Mermaid was published in Copenhagen.

What the evidence tells us

Royal Museums Greenwich shows how mermaids appear in art and sea stories. NOAA reports that no evidence of half-human aquatic beings has been found. Our shy mermaid is a fictional character; real coastal wildlife has its own remarkable lives.

Your turn to investigate

Compare two mermaid illustrations. Which details belong to the artist’s choices, and which would you need to observe in a real animal?

A connection to real nature

A whole world in a tide pool

A tide pool is part of a living coastal habitat. Leave its animals, shells, seaweed, and stones where they are. A grown-up can help choose a safe place to watch the changing water.

Try noticing

Look from the edge. Which creatures cling to rocks? Which hide in the water? Have a grown-up check tides and local safety advice before you go.
