Tag Archives: Anisodoris nobilis

All Nudibranchs are beautifully colored, but this is a new one for me. Liam Ericson found this Nudibranch off the Point Arena-Stornetta Lands.

Robert Van Syoc took a look at Liam's photo. He wrote, “It’s Anisodoris nobilis, sometimes called the Sea Lemon. They feed on sponges and repurpose noxious chemicals in the sponge tissue as their own defense against predation. They taste bad to fish! The bright showy coloration of most nudibranchs evolved as warning coloration to predators.”

The Sea Lemon, so bright yellow, has a white flower on one end - a nice touch by Mother Nature.

Thanks to Liam for allowing me to share his photo with  you here and Bob for sharing his expertise.

Waiting for another storm to come in later tonight. Not a big one, but we always welcome the wet stuff.
