Kelp fronds and pneumatocysts. Pneumatocysts, gas-filled bladders, float the kelp off the ocean bottom toward the surface and sunlight, where the leaf-like blades and stipes of the kelp plant grow fastest.

Garibaldi and California golden gorgonian on underwater rocky reef, San Clemente Island. The golden gorgonian is a filter-feeding temperate colonial species that lives on the rocky bottom at depths between 50 to 200 feet deep. Each individual polyp is a distinct animal, together they secrete calcium that forms the structure of the colony. Gorgonians are oriented at right angles to prevailing water currents to capture plankton drifting by.

Giant black sea bass in the kelp forest at Catalina Island. An Endangered Giant Sea Bass can reach up to 8 feet in length and 500 pounds, seen here amid the giant kelp forest of Catalina Island. Once nearly fished to extinction and now thought to be at risk of a genetic bottleneck, the giant sea bass is slowly recovering and can be seen in summer months in California's kelp forests.

Two giant black sea bass swim in a courtship circle, part of a larger gathering of a mating aggregation amid kelp forest, Catalina Island. In summer months, black seabass gather in kelp forests in California to form mating aggregations. Courtship behaviors include circling of pairs of giant sea bass, production of booming sounds by presumed males, and nudging of females by males in what is though to be an effort to encourage spawning.

Giant kelp frond showing pneumatocysts. Small gas bladders -- pneumatocysts -- connect the kelp's stipes ("stems") to its blades ("leaves"). These bladders help elevate the kelp plant from the bottom, towards sunlight and the water's surface.
