Kelp bass, giant kelpfish, garibaldi, norris' top snail, and kelp crabs are all common inhabitants of the kelp forest. Kelp anchors to the rocky bottom with a structure called the holdfast. The holdfast has many crevices and is home to many other animals such as spiny brittlestars and amphipods. The leaf-like kelp blades (also called fronds) provide a large surface area for photosynthesis. On the blades themselves, a bryozoan can grow rapidly and completely cover a kelp blade within 3-4 weeks.
