A kelp forest is a unique underwater ecosystem formed by large, brown seaweeds known as kelp. These forests thrive in nutrient-rich, shallow waters along coastlines, providing habitat and food for a diverse range of marine life, including fish, sea urchins, and sea otters. Kelp can grow rapidly, reaching heights of up to 100 feet, and plays a crucial role in coastal protection and carbon absorption. Kelp forests are important for both ecological balance and human activities. They support commercial fisheries and recreational activities like diving and snorkeling. Additionally, these ecosystems help maintain water quality and provide shelter for many species, making them vital to ocean health.
