The Kelp Forest offshore of La Jolla, California. A kelp forest. Giant kelp grows rapidly, up to 2' per day, from the rocky reef on the ocean bottom to which it is anchored, toward the ocean surface where it spreads to form a thick canopy. Myriad species of fishes, mammals and invertebrates form a rich community in the kelp forest. Lush forests of kelp are found throughout California's Southern Channel Islands.
Species: Giant kelp, Macrocystis pyrifera

Aerial photo of blue whale with a rainbow in its blow (spout), near San Diego. This enormous blue whale glides at the surface of the ocean, resting and breathing before it dives to feed on subsurface krill.

Male elephant seals (bulls) rear up on their foreflippers and fight in the surf for access for mating females that are in estrous. Such fighting among elephant seals can take place on the beach or in the water. They bite and tear at each other on the neck and shoulders, drawing blood and creating scars on the tough hides.
Species: Elephant seal, Mirounga angustirostris
Location: Piedras Blancas, San Simeon, California

Kelp fronds showing pneumatocysts, bouyant gas-filled bubble-like structures which float the kelp plant off the ocean bottom toward the surface, where it will spread to form a roof-like canopy.

Sunlight glows throughout a giant kelp forest. Giant kelp, the fastest growing plant on Earth, reaches from the rocky reef to the ocean's surface like a submarine forest.

Kelp fronds and pneumatocysts. Pneumatocysts, gas-filled bladders, float the kelp plant off the ocean bottom toward the surface and sunlight, where the leaf-like blades and stipes of the kelp plant grow fastest. Giant kelp can grow up to 2' in a single day given optimal conditions. Epic submarine forests of kelp grow throughout California's Southern Channel Islands.

Courting pair of southern right whales underwater, Eubalaena australis. While the posture in this photo isn't quite mating, it is a courting behavior that often precedes mating. The male is below, upside down and trying to access the female belly-to-belly. However, the female does not want to mate, so she has positioned herself upside down at the surface so that the males in the courting group cannot reach her genital slit.
Species: Southern Right Whale, Eubalaena australis
Location: Puerto Piramides, Chubut, Argentina

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.
