About Pleurobranchaea californica MacFarland, 1966
Pleurobranchaea californica is a species of gastropod in the family Pleurobranchaeidae. This species occurs along the western coast of North America. Pleurobranchaea californica are voracious predatory sea slugs. For localized feeding, they rely on chemical signal cues detected by chemical receptors that line the anterior edge of their veil. They also exhibit aposematic learning, which allows them to avoid animals that have noxious defenses.
