웹If barnacles did not have their adaptations to the intertidal zone they’d live in the low tide zone meaning they’d have more submergence time. This means other predators would feed on the barnacles and leave the oyster borer with not much food source, causing the oyster borer to be less likely to survive, meaning they would not have their ecological niche. 웹Barnacles of the typical size of a chthamalid (ca. 1 cm in diameter) are difficult to evaluate in this regard, but Southward (1964) studied cirral activity (feeding rate) in a number of chthamalid ...
