Janolus barbensis is a commonly found nudibranch on the Pacific coast inhabiting tide pools of La Jolla, California. Populations also expand to some parts of Costa Rica. The dorsal side of the body is transparent white, while the tip of its cerata is ringed with blue coloration. Underlying the blue ring, is another band shaded gold that covers the papillae. The papillae epithelium is smooth with split papilla ducts. Anal glands are present in this particular species along with small oral glands located on the anterior end. 7-9 denticles envelop the jaws with smooth rachidian and two inner denticulate. Seminal vessels are characteristically short, spherical, and serial. Other reproductive ducts are diaulic.
