(1) Lack of recruitment rather than predation and competition after metamorphosis keeps Balanus pacificus out of the interiors of large rocky areas. (2) Availability of cleared substrate sets an upper limit on the abundance of B. pacificus. (3) Competition after metamorphosis is unimportant in determining abundance in the areas where B. pacificus is common. (4) Predation by two species of polyclad flatworms is the major cause of mortality in B. pacificus populations.
