(1973) Long-term sensitization of a defensive withdrawal reflex in Aplysia, Science, 182, pp. Their well-developed nervous system is controlled by these ganglia. But there, too, oysters and mussels dont violate any code. This means that the snails can become sensitized to noxious stimuli after they are exposed to it and they react more strongly to subsequent exposures.33 Snails are also capable of this form of learning.34 These types of learning (sensitization and learning by association) might be some of the simplest forms of reaction to noxious stimuli, with even single celled organisms arguably showing some level of this.35 These forms of learning constitute only weak evidence of sentience at best because they can be explained by simple mechanisms.

Scallops are also a major commercially harvested seafood; certain species (Placopecten magellanicus, Aequipecten irradians, and A. opercularis) are highly prized. Clams, like all invertebrates, are not motile and do not have a brain. Scallops do not have a central nervous system, so they cannot feel pain. Oysters also fall into the category of bivalves as they have also a hinged shell to safeguard their soft organs inside. As water enters the scallop, mucus traps plankton in the water, and then cilia move the food into the scallop's mouth. Their mucus is extracted through the process of milking, which consists of putting salt or acid on a snail so the snail secretes slime as a defense mechanism.
