California is known for epic kelp diving but the waters can be a bit chilly for tropical divers like myself. Looking for a quick summer dive trip close to home, I finally grew some skin and booked a trip with Truth Aquatics to the Channel Islands – my first truly temperate dive experience. My only regret…I shouldn’t have waited so long!
Beneath the surface, kelp takes on a magical appearance. The gently swaying fronds create an undersea jungle of incredible beauty. Swimming through a dense kelp forest for the first time is like being on a safari, offering the promise of surprising animal encounters.

Even common fish species, like California sheephead (Semicossyphus pulcher ), kelp bass ( Paralabrax clathratus ), giant kelpfish (Heterostichus rostratus) , giant sea bass (Stereolepis gigas ), Catalina goby (Lythrypnus dalli) and Garibaldi (Hypsypops rubicundus ), leave a lasting impression under the incredible backdrop of the unique kelp forest ecosystem. Here are my favorite images about the marine life of the Channel Islands :

Senorita (Oxyjulis californica) tends to schooling Halfmoon(Medialuna californiensis). The señorita is a cleaner wrasse, a fish that grooms the parasites and other materials off the bodies of other fish. California. Senorita

Spawning senorita (Oxyjulis californica). I saw this species aggregate into large schools near drop offs during the midday and then spawn in smaller groups of 20-30 individuals. Senorita spawn from May through August. California. Senorita

Juvenile giant kelpfish (Heterostichus rostratus) - still mostly transparent. Note the visible gut and air bladder. The young fish school in the kelp canopy and remain relatively transparent until they become solitary at about 3 inches. California. Kelpfish
