Sponges (Porifera) are sessile filter feeders that are able to accumulate compounds from the surrounding water and thus are highly exposed to environmental stress by pollutants of both anthropogenic and natural origin. However, these animals possess a number of protective mechanisms against environmental stress, such as the expression of heat-shock proteins, the induction of the multi xenobiotic resistance mechanism, and the apoptotic elimination of cells. In the last years, a number of genes involved in the stress response of sponges have been cloned and characterized. In thischapter, the various molecular mechanisms by which cells of the lowest multicellular organisms—the marine sponges—respond to environmental stress and the methods for measurement of stress response in sponges are discussed.
