Wave energy, Complex 3D habitat - biologically diverse What Are The Sea Otters Indirect Effects? It does not store any personal data. Water clarity is a measure of how far down light can penetrate through the water column. Unlike intertidal sea urchins that live solitary lives in crevices, waiting for a piece of kelp to drift by, subtidal urchins live together in hordes. HABITAT. Because kelp attaches to the seafloor and eventually grows to the waters surface and relies on sunlight to generate food and energy, kelp forests are always coastal and require shallow, relatively clear water.
