Imagine you're scuba diving underwater through a giant kelp forest. Wild, wavy plants are all around you. Look down. Chances are you can't see the bottom. That's because giant kelp can grow up to 60 metres/200 feet high. They can even grow as much as 15 centimeters/6 inches each day. But if you could see further down you would see that kelp plants have no roots, stems, leaves or flowers like an earthly plant. Here's the scoop: Kelp are actually large brown algae.

Are you still scuba diving? Do you see all the different kinds of plants and animals that form the kelp forest community? Like trees, kelp provide living space, food and protection for all sorts of creatures. Animals like sea stars, sea urchins, sea cucumbers, snails, fish and sea otters thrive in kelp habitats. Are you chilly yet? It's probably time to get out of the water. Kelp grows in the cool waters of many oceans including the pacific coast of North America and the coasts of Tasmania and Victoria, Australia.
