Abstract
Aplysia californica when prefed a partial meal of nonnutritional bulk eat significantly less food compared to control animals. The total mass of material consumed by animals fed bulk and then fed to satiation with seaweed was not significantly different from the mass consumed by animals fed to satiation with seaweed alone. In a second experiment, animals were fed daily, alternating weekly periods of feeding animals 50% diluted food with periods of feeding animals nutritionally normal meals. The nutritional content of diluted meals was significantly less than the nutritional content of undiluted meals. The mass of material consumed was not significantly different for diluted compared to nondiluted meals. These experiments indicate that the bulk properties of food play an important role in producing satiation in Aplysia.
