Phenotypic changes
WebPhenotypic variation is an important adaptive mechanism in rotifers, but has posed difficult problems for systematists. This variation arises by several mechanisms including cyclomorphosis, dietary- and predatorinduced polymorphisms, polymorphisms in hatchlings from resting eggs, and dwarfism.
