| Polydora hoplura bored into the shells of cultured native abalones, Haliotis tuberculata coccinea, creating holes in the shell, chimneys on the shell-surface, and inducing the formation of blisters, causing breakage of some of shells and death of the abalones. The worm infestations were controlled by the drug Mebendazole, which did not affect the growth of the abalones (Bilbao et al. 2011). | ||
