Abstract: | Chemical communications play an important role in plants, fungi, and algae. Volatile organic compounds in marine algae are
released into the seawater. These compounds play a role as either pheromones or allelochemicals. We observed that the turbinid
gastropod Lunella coronata coreensis inhabits the intertidal zone and often grazes the green alga Ulva pertusa. Feeding tests and feeding preference studies were performed with green, brown and red algae or by using the powdered freeze-dried
seaweed in agar. The snails fed on U. pertusa preferentially compared to the other marine algae, and recognized chemoreception compounds from the alga but not their structural
or morphological differences. From feeding tests using artificial foods, it is suggested that the feeding attractants are
in the essential oil of the alga U. pertusa. |
