This study documents the distribution of six limpet species occurring in Port Valdez, Alaska, and the reproductive cycle and shell growth patterns for one of those species, Tectura persona (Rathke, 1833). The distribution of the limpets observed in Port Valdez shows similarities to that described for the same species elsewhere. The abundance of Tectura fenestrata (Reeve, 1855) was associated with
... [Show full abstract] changes in environmental variables suggesting downward migration or increased cryptic behavior in winter. Reproductive activity (including developmental stages) was present in T. persona throughout the year. Shell growth of T. persona appears to be relatively slow and the longevity of limpets moderate. During this study, no effects of oil contamination on limpet abundance were apparent for limpets near an oil terminal.
