No, the Black Sea is not a lake. The Black Sea is an example of an inland sea. The Black Sea is at sea level, and it is open to the ocean.

Farthest Inland Port

• Port of Duluth, Minnesota, USA.
• Iquitos, Peru.
• Yibin, China.

seas that extend deep within the boundaries of one continent. They are a particular case of mediterranean seas. Examples of inland seas are the Baltic and White seas, the Sea of Azov, and Hudson Bay.

Inland seas, also called epeiric or epicontinental seas, are shallow seas over part of a continent. They usually happen with marine transgressions, when the sea overtops the land.

Inland Seas Of The World

• What Is an Inland Sea? One characteristic that defines all inland seas is their shallow depths, with none reaching more than 2,000 feet in depth.
• The Hudson Bay.
• The Baltic Sea.
• Prehistoric Inland Sea.

The Seven Seas include the Arctic, North Atlantic, South Atlantic, North Pacific, South Pacific, Indian, and Southern Oceans.

Arctic Ocean

Atlantic Ocean

• Hudson Bay. James Bay.
• Baffin Bay.
• Gulf of St. Lawrence.
• Caribbean Sea.
• Gulf of Mexico.
• Sargasso Sea.
• North Sea. Baltic Sea. Gulf of Bothnia.
• Irish Sea.

The largest terrestrial seas are:

• Australasian Mediterranean Sea – 9.080 million km.
• Philippine Sea – 5.695 million km.
• Coral Sea – 4.791 million km.
• American Mediterranean Sea – 4

The following is a list of those seas arranged by area.

• Philippine Sea. Area: 2,000,000 square miles (5,180,000 sq km)
• Coral Sea. Area: 1,850,000 square miles (4,791,500 sq km)
• The South China Sea. Area: 1,350,000 square miles (3,496,500 sq km)
• Tasman Sea.
• Bering Sea.
• The East China Sea.
• The Sea of Okhotsk.
• Yellow Sea.

Pure ocean water lying far away from coasts beyond continental shelf looks darker than the costal water that has several constituents. This is so because colour of pure water is decided by Rayleigh scattering that makes it blue. Coastal waters have phytoplankton, suspended sediments and yellow organic dissolved matter.

Asia is bounded by the Arctic Ocean to the north, the Pacific Ocean to the east, the Indian Ocean to the south, the Red Sea (as well as the inland seas of the Atlantic Ocean—the Mediterranean and the Black) to the southwest, and Europe to the west.

The following table lists the world’s oceans and seas, according to area and average depth, including the Pacific Ocean, Atlantic Ocean, Indian Ocean, Southern Ocean, Mediterranean Sea, Arctic Ocean, Caribbean Sea, Bering Sea, and more.

Pacific Ocean

The sea was first named by the ancient Greeks who called it “Inhospitable Sea.” The sea got this reputation because it was difficult to navigate, and hostile tribes inhabited its shores. Later, after the successful development of the coast by Greek colonists, the sea was renamed “Hospitable Sea.”

The Black Sea is home to world’s biggest, most productive spiny dogfish sharks, but this remarkable, global species is in danger of extinction. CITES action is needed to curb unsustainable trade … before it’s too late. What is a spiny dogfish?

With a clean fresh water surface, swimming in the Black Sea is possible; though offer a different experience from other water bodies. With its strange features, including the high level of minerals and salt, normally the objects tend to float on the water.

With rivers providing an abundant supply of fresh water, the upper layers of the Black Sea are less dense than its saltier lower layers. Furthermore, a high concentration of hydrogen sulfide, an extremely toxic gas, lies dormant in the deepest layers of the Black Sea.

The Black Sea coastline is also heavily polluted with plastic; 14% of the waste that contaminates its beaches consists of plastic bottle caps, 6% wrappers, 5% bottles and 2% straws and stirrers.

Black sea, blue river, green mountains Bears, wolves and lynx inhabit the old growth forests. In the Black Sea, one still finds bottlenose dolphins and about 180 species of fish, including tuna, anchovy, herring, mackerel and the famous white sturgeon.

A few species that can be annoying are listed below.

• Rhizostome jellyfish Rhizostoma pulmo can sting your skin with its thread-cells located on the lacy peristomal tentacles.
• Moon jellyfish Aurelia aurita is another Scyphozoan medusa common in the Black Sea.
• Black Sea scorpion-fish Scorpaena porcus.

The most diverse and interesting marine life of the Black Sea is in the rocky bottom habitats. In very shallow water, we find multicolored macroalgae, motley bright blennies, shrimps, and sea anemones.

Estimates of dinoflagellate diversity in the Black Sea range from 193 to 267 species.
