Plants in seas and oceans can be hard, soft, slimy or even delicious. Sea plants grow in every colour and often have weird names like "sea lettuce" and "devil's apron.
" Hundreds of species grow all over the world, but sea kelp is a special kind of ocean plant, the largest and the most critical plant to the survival of many endangered sea animals.
What does kelp look like?
Kelp is a large greenish-brown plant that can grow more than 45 metres tall. It has many leaves, called "blades," which are shaped like swords. To grow so tall, each blade at the top of the kelp splits into two. At the base of these blades, the plant has "bladders," little ball-shaped pods that are filled with air and gas. These bladders help the kelp stay upright so the tops can reach the sunlight.

Where does sea kelp grow?
You won't find kelp growing around the UK's coasts. It is found in the Pacific ocean, most commonly near Western Australia, Japan, Mexico and California. Kelp thrives in cold water with lots of waves or a strong current; this turbulence brings to the kelp the nutrients necessary for its survival. To reproduce, the kelp creates tiny spores that float away to create new kelp and, eventually, a kelp forest.

What animals live in kelp forests?
The canopy and sea bottom of the kelp forests house crabs, eels, sea sponges and many varieties of fish. The most interesting animal among the kelp may be the weedy sea dragon, which is a kind of seahorse that looks just like a floating piece of seaweed. Large animals like to hang out in the kelp too, such as dolphins, turtles and sharks. The giant sea otter, an endangered species, is often found in areas with a lot of kelp.

Why is kelp important?
Kelp shelters a number of sea creatures, some of which are endangered. The inhabitants of the kelp forests eat the blades for vital energy. Some of these creatures are also food for bigger ones; for example, sea otters eat sea urchins, which in turn can eat an entire kelp forest if no otters are around to keep them under control. Many fish will hide from predators in the kelp forests or may use its shade to raise a family.
