What is the continental shelf marine life?

Lobster, Dungeness crab, tuna, cod, halibut, sole and mackerel can be found. Permanent rock fixtures are home to anemones, sponges, clams, oysters, scallops, mussels and coral. Larger animals such as whales and sea turtles can be seen in continental shelf areas as they follow migration routes.

How is sea life on the continental shelf?

Sunlight penetrates the shallow waters, and many kinds of organisms flourish—from microscopic shrimp to giant seaweed called kelp. Ocean currents and runoff from rivers bring nutrients to organisms that live on continental shelves. Plants and algae make continental shelves rich feeding grounds for sea creatures.

Why does the continental shelf have the most marine life?

The shallow, sunlit waters of the continental shelf are flooded with nutrients, supporting an abundance of sea life. Many animals live here.

How much sea life lives over the continental shelf?

Ninety percent of the world’s fish are found along the continental shelf.

What is the continental rise marine life?

The continental rise is the gently inclined slope between the base of the continental slope and the deep ocean floor. It overlies the ocean crust bordering the faulted and fractured continental margin. It is the ultimate site of accumulation of sediment shed from the continent into the deep sea.

What is an example of a continental shelf?

Example of a Continental Shelf Landform: Siberian Shelf, Arctic Ocean. The picture is of Southeast Florida Continental Shelf (It is under water). It is smaller than the side in the Gulf of Mexico.

Why is continental shelf important?

The significance of the continental shelf is that it may contain valuable minerals and shellfish. UNCLOS addresses the issue of jurisdiction over these resources by allocating sovereign rights to the coastal State for exploration and exploitation.

How long is the continental shelf?

A continental shelf typically extends from the coast to depths of 100–200 metres (330–660 feet). It is gently inclined seaward at an average slope of about 0.1°. In nearly all instances, it ends at its seaward edge with an abrupt drop called the shelf break.

What marine life lives in the continental slope?

Different Slope Communities

Dover sole, sablefish, and rockfish (fig. 4) have this type of life history; however, most species living deeper, such as rattails, deep-sea soles, and slickheads, have young that live in the same depths as adults. Relatively few species occur at all or most depths on the Continental Slope.

Why are continental shelves under the ocean?

At active margins, the movement of Earth’s plates causes earthquakes and volcanic activity. This activity shapes continental shelves around much of the Pacific Ocean, where shelves are often very narrow, so that sediment may get dumped into deep ocean trenches.

Where is the continental shelf?

A continental shelf is the edge of a continent lying beneath the ocean. This shelf extends from the coastline of a continent to a drop off point called the shelf break.
