California is known for its extensive kelp forests along its Pacific Coast, which support diverse marine ecosystems.

California has some of the most well-known kelp forests along its Pacific Coast. These underwater forests, primarily composed of giant kelp, create highly productive ecosystems that support a variety of marine species, including fish, sea otters, and sea urchins. Kelp forests thrive in the nutrient-rich waters of the California coast and play a crucial role in carbon sequestration and coastal protection. While Alaska also has kelp forests, California's coastline is particularly famous for these ecosystems. Florida and Maine are not known for kelp forests; instead, they have other coastal ecosystems like seagrass beds and salt marshes.
