Abstract: 1. Tegula funebrals will ingest nearly any alga growing in or out of the littoral zone. Both macroscopic and encrusting forms constitute important food sources; the granite surfaces contain a negligible amount of organic detritus and contribute little to the diet of the animal. Earlier work on T. funebralis and observations of T. gallina show that the animals will ingest organic detritus when it is available. 2. The snail prefers a "fleshy" alga among macroscopic forms (eg Macrocystis integrifolia, Nereocystis luetkeana, and Gigartina canaliculata). 3. Feeding rates per gram are greater in the smaller animals and apparently not affected by lack of sunlight. 4. A short field suggests the importance of the feeding activities of Tegula funebralis on the local algal crops.
