The Arabian Sea formed 45-60 million years ago as a result of tectonic activity.
The sea has a monsoon-type climate with hot, humid summers and not-so-cold winters, with monsoonal winds bringing heavy rainfall.
It has been referred to by different names throughout history, such as Akhzar Sea, Bahre Fars, and Hindu Sea.
It has many important ports and harbours, such as Jawaharlal Nehru Port, Mumbai and Port of Karachi.
Socotra Island, located in the western part of the sea near the Gulf of Aden, is the largest island in the Arabian Sea and has unique endemic flora and fauna.
It has two main basins, the Arab Basin and Somali Basin, separated by Carlsberg Ridge.
The Arab Basin is significantly deeper than the Somali Basin and is one of the world's deepest ocean basins with many canyons and channels.
It is an important water body for maritime trade and supports numerous aquatic species, with millions depending on its fisheries for their livelihoods.
