Abstract
    Characteristic seasonal cycles have been found for interstitial opisthobranchs living in various sandy biotopes of different exposure in the Gulf of Marseilles (Mediterranean coast of France). Abnormal progressive degradation of the environment caused by increased pollution and a striking decrease of regional wind frequency throughout a seven-year period changed these cycles. The sensitivity of these interstitial opisthobranchs to the degradation of their habitat makes them valuable biological indicators which could be used to identify clean sublittoral sandy bottoms which need to be protected.
