Some marine biologists think that kelp forests provide habitat for as many different type of wildlife as does a tropical rain forest on land. Both kelp forests and rain forests have hundreds of different types of
plants, animals and insects living in them. Worms, snails, crustaceans, and mollusks also live in the kelp forest.
Bottom fish live at the base of a kelp forest. Lots of the fish and other animals that
live in kelp beds attract predators. Sharks, seals, and sea otters find these forests to be great hunting areas. Kelp is commercially harvested for lots of products that are used by people. Kelp has a
chemical called algin. Algin is used as a thickener, stabilizer, and emulsifier. Thinkeners increase a substances density by making the substance less watery. Stabilizers prevent foods from getting rotten and
emulsifiers help ingredients from separating. Algin from kelp is used in ice cream and lots of other dairy products as well as in many kinds of processed foods, beverages, and medicines. Algin is also used for
making paper, cometics, ceramics, paint, and insecticides.
