The sea that separates the Arabian Peninsula from Africa is the Red Sea. This seawater inlet of the Indian Ocean is known for its stunning coral reefs, rich marine biodiversity, and significant historical trade routes. The Red Sea extends about 2,300 kilometers long and connects to the Mediterranean Sea via the Suez Canal to the north. It plays a crucial role in international shipping and is a major destination for diving enthusiasts due to its clear waters and vibrant aquatic life.
