what is the symmetry of gooseneck barnacles
They receive minimal exposure to water; at the most, once a day. They are most often found within cracks and crevices in rocks to minimize their exposure to sunlight, which helps prevent desiccation. Pollicipes polymerus is most commonly found in colonies of many other gooseneck barnacles.ollicipes polymerus is a hermaphrodite, meaning it is equipped with both male and female reproductive organs. These organs mature at relatively the same rate in the gooseneck barnacles. Although it is hermaphroditic, it usually will not self-fertilize unless there are no other barnacles within about eight inches.
