This sea is surrounded by many different lands and islands. To the west, you will find the islands of Corsica and Sardinia. The Italian Peninsula forms the north and east sides. Sicily sits at the southern edge of the sea. Many smaller islands like Capri and Elba also live here.

The sea is named after the Tyrrhenian people. These people were also known as the Etruscans.

This sea was formed in a special way. Scientists call it a back-arc basin. It formed when a piece of the Earth's crust moved. This happened during a time called the Neogene. As this piece moved, it created two flat areas. These are called the Vavilov plain and the Marsili plain. An undersea ridge called the Issel Bridge separates them.

This ridge is named after a person named Arturo Issel. This movement also helped create underwater volcanoes.

Deep under the water, things are very active. The sea sits near where the African and Eurasian plates meet. This meeting of plates creates mountain chains and volcanoes. One famous underwater volcano is called Mount Marsili. There is also a deep place called the Caprera Canyon. It sits 1,000 metres below the surface.

A group called The One Ocean Foundation explored this canyon. They found rare sponges, corals, and many kinds of fish.

History tells us about the people who lived nearby. A Greek writer named Hesiod wrote about them long ago. He lived in the 8th century BC. He said the Etruscans lived in central Italy. They lived near the Latins. The Etruscans called this water the "Sea of the Etruscans."

Today, many people use the sea for travel. Big ports like Naples and Palermo help move goods. Even the city of Rome uses a port at Civitavecchia.

Nature in the sea is beautiful but faces hard jobs. Many fish and corals in the canyon are at risk. This is because of pollution from travel. Another problem is called bottom trawling. This is a type of fishing that can hurt the ocean floor.
