Dolphins are found in seas and oceans all over the world. They typically live in shallower waters along the continental shelves, but this isn't always the case. According to Sea World, dolphins can be found in seas including, but not limited to, the Mediterranean Sea, Black Sea and Red Sea. Additionally, the dolphin can be found in all the world's oceans.
Which dolphins inhabit which seas often depends on the species, but there are other relevant factors. One of the most popular and well-known species, the bottlenose, is commonly found in the Mediterranean and Black Seas. A sub-variety, the Indo-Pacific bottlenose, can be found throughout the Indian Ocean and up north in the Red Sea. In the South China Sea, there are populations of the increasingly diminished Chinese White Dolphin, a species which has gained greatr attention from conservationists. At one time, there were around 20 discrete populations of the Chinese White. As of the beginning of the 21st century, only five remained. In the Caribbean Sea and Gulf of Mexico, Clymene dolphins are common. The Clymene, also known as spinner dolphins, are recognized by their shorter snouts. They frequently have darker patterns noticeable on their dorsal fins and around the eyes. While the majority of dolphin species favor warm tropical or sub-tropical waters, they have been known to migrate into colder regions when need be, particularly when their food supply migrates first. Additionally, while dolphins most commonly inhabit salt-water habitats, they have also been found in freshwater locations and estuaries.
