Underwater kelp forests exist all over the world and host a vast array of life. They can grow at depths up to 150 feet and still reach the surface with some giant kelps growing up to two feet in a day.

The seaweeds that form kelp forests are a special group of brown algae that attach themselves to solid structures such as rock, and extend their leaves into the waters above them as they reach towards the sunlight.
These larger algae in turn create a habitat for smaller algae and a wealth of animals that can either live attached to the rocks beneath the kelps, on the kelps themselves, or in the sheltered waters between individual plants.
