Here are a few Gulfs you may know ...
The Gulf of Aden (Arabic: خليج عدن Ḫalīǧ ʻAdan, Somali: Gacanka Cadmeed) is located in the Arabian Sea between Yemen, on the south coast of the Arabian Peninsula and Somalia. In the northwest, it connects with the Red Sea through the Bab-el-Mandeb strait, which is about 20 miles wide. The waterway is part of the Suez Canal shipping route between the Mediterranean Sea and the Arabian Sea in the Indian Ocean. The gulf is known by the nickname "Pirate Alley" due to the large amount of pirate activity in the area.*
The Gulf of Mexico (Spanish: Golfo de México) is a partially landlocked ocean basin largely surrounded by the North American continent and the island of Cuba. It is bounded on the northeast, north and northwest by the Gulf Coast of the United States, on the southwest and south by Mexico, and on the southeast by Cuba.*
The Gulf of Nicoya (Spanish: Golfo de Nicoya) is an inlet of the Pacific Ocean. It separates the Nicoya Peninsula from the mainland of Costa Rica, and encompasses a marine and coastal landscape of wetlands, rocky islands and cliffs.*
