GEOGRAPHICAL FEATURES
The Caspian Sea is the world's largest inland body of water and is bordered by five countries: Russia, Kazakhstan, Turkmenistan, Iran, and Azerbaijan. It is a landlocked endorheic (having no natural outflow except evaporation) sea between Asia and Europe.The sea has several notable geographical features, including:
Size and depth: The Caspian Sea is the world's largest inland body of water, covering an area of approximately 371,000 square kilometers (143,000 square miles) and with an average depth of 211 meters (692 feet)
Coastline: The coastline of the Caspian Sea is approximately 4,000 miles (6,400 kilometers) long and features a mix of sandy beaches, cliffs, and marshy areas.
Depressions: The Caspian Sea is situated in a large depression, which has resulted in a relatively low elevation compared to sea level. The sea is also surrounded by several other large depressions, including the Caspian Depression and the Ustyurt Plateau.
Volcanic islands:
The Caspian Sea has several coastal wetlands, including the Miankaleh Peninsula in Iran and the Kizlyar Bay in Russia, which are important habitats for migratory birds and other wildlife.
Depressions:
Over 130 rivers provide inflow to the Caspian, with the Volga River being the largest. A second affluent, the Ural River, flows in from the north, and the Kura River flows into the sea from the west. In the past, the Amu Darya (Oxus) of Central Asia in the east often changed course to empty into the Caspian through a now-desiccated riverbed called the Uzboy River, as did the Syr Darya farther north.
ISLANDS
Number of islands in the Caspian Sea is not well-defined as there are numerous small islands, some of which may not even have a name. However, there are several larger islands in the Caspian Sea that are notable for their size or their geological features. The largest islands in the Caspian Sea are:
Ogurja Ada Island: Located in the northern part of the Caspian Sea and is the largest island with an area of about 730 square kilometers.
Chechen Island: Located in the southeastern part of the Caspian Sea and has an area of about 500 square kilometers.
Tyuleniy Island: Located in the northern part of the Caspian Sea, it is known for its active volcanoes and is a protected nature reserve.
Ashuradeh Island: Located in the southwestern part of the Caspian Sea and is the only island in Iran's territory. It is a protected area and an important habitat for migratory birds.
Pirallahy Island: Located in the southeastern part of the Caspian Sea and is divided between Iran and Turkmenistan.
There are many other smaller islands in the Caspian Sea, some of which are inhabited, while others are uninhabited and serve as important habitats for wildlife.
Volcanic islands: There are several volcanic islands in the Caspian Sea, including Tyuleniy Island, which is home to several active volcanoes.
MARINE LIFE
The Caspian Sea is home to a variety of species of fish, including sturgeon, Caspian salmon, carp, and catfish. Sturgeon is one of the most important fish species in the Caspian Sea, as it is the source of caviar, a delicacy that is highly valued around the world.
However, the Caspian Sea is also facing environmental challenges that are threatening its marine life. Pollution, overfishing, and the introduction of invasive species are some of the biggest threats to the ecosystem of the Caspian Sea.
The Caspian sea is home to a unique and diverse array of marine life. Some of the notable marine species found in the Caspian Sea include:
-
Caspian Seal: The Caspian seal, also known as the seal of Iran, is a unique species of seal that is found only in the Caspian Sea. It is the only mammal species in the Caspian Sea.

Sturgeon: The Caspian Sea is home to several species of sturgeon, including the beluga sturgeon, which is famous for its prized caviar. These fish are important both economically and ecologically, but have been heavily impacted by overfishing and habitat destruction.
-
Kilka Fish: Kilka fish, also known as Caspian sprat, are small, silvery fish that are abundant in the Caspian Sea. They are an important food source for many larger fish and marine mammals, as well as for humans.
-
Jellyfish: The Caspian Sea is home to several species of jellyfish, which play an important role in the ecosystem as both predators and prey.
-
Crustaceans: The Caspian Sea is home to a variety of crustaceans, including several species of shrimp and crab. These animals are important both ecologically and economically.
-
Dolphins: The Caspian Sea is home to a small population of bottlenose dolphins, which are found only in the northern part of the sea. The population is critically endangered due to a range of factors, including pollution, habitat destruction, and hunting.
Conservation efforts are underway to protect the marine life of the Caspian Sea, including efforts to reduce pollution, limit overfishing, and protect critical habitats. These efforts are important not only for the survival of the unique and diverse marine life of the Caspian Sea, but also for the millions of people who depend on the sea for their livelihoods and well-being
