Unique Bay habitats include Marina del Rey, Torrance Beach, and Short Bank. Marina del Rey and King Harbor are enclosed, artificially deepened habitats that harbor calm-water organisms. The Torrance Beach area is a nursery ground for juvenile California halibut that extends north to the head of Redondo Submarine Canyon. Short Bank is the only natural deep-water hard bottom area in the Bay.
Ecological reserves have been proposed for the regions between Paradise Cove and Malibu Point, and from Palos Verdes Point to Flat Rock on the Palos Verdes Shelf. Also, the area from the Ventura-Los Angeles County Line south to Point Dume is considered an area of special biological significance by the California Ocean Plan.
