Student Author(s): Popov, Dragan
Location: Final Papers Biology 175H
Date: June 1980
Keywords: symbiosis at the seashore
Abstract: 1. There are direct positive correlations between infection by shell borers, shell density and the breaking point of abalone shells. 2. Cliona celata bores into all species studied with the greatest infection in H. rufesens and the least in H. cracherodii. 3. Penitella conradi has lowest infection rates in H. cracherodii and highest rates in H. rufesens, H. fulgens and H. corrugata. 4. Penitella and Cliona have distinct boring patterns and damage the shell in different ways.
