No coral reefs are found in the Pacific Coast waters due to colder temperatures, though vibrant marine ecosystems like kelp forests thrive there.

The Pacific Coast’s colder waters do not support coral reefs, which typically thrive in warmer, tropical seas. Instead, the coastline is home to rich marine ecosystems, including vast kelp forests and diverse marine life. These kelp forests provide shelter, food, and breeding grounds for many species, making them essential to the coastal environment. From Southern California to Alaska, these underwater forests play a critical role in supporting biodiversity and sustaining fisheries. While coral reefs are absent, the Pacific Coast's unique habitats offer natural beauty and ecological importance, drawing marine biologists, divers, and nature enthusiasts to explore its underwater landscapes.
