First dive trip since November, thought you might enjoy seeing some nudibranch shots. Macro camera died second day into the three day Channel Islands trip [July 2005]. This Janolus barbarensis was shot on a night dive at Catalina, California.

Thanks for these great photos. Can anyone tell me if the bryozoan at the top of the photo alongside is the food of this species?

We were out photographing branchs and other great marine life all weekend, out at our local Southern California Islands. Check out the jewel of the California branchs, Janolus barbarensis, with its gold and sapphire tipped cerata, what an incredible animal. These are two animals I photographed in about 90 feet of water at a place called Farnsworth Banks. Farnsworth was loaded with Janolus as well as six other species we photographed.
Have a great week and let me know if there is anything else we can do for you,

It is indeed a beautiful species.
