Paraconcavus pacificus (Pilsbry, 1916)
Balanus glandula is one of the most common barnacle species on the Pacific coast of North America, distributed from the U.S. state of Alaska to Bahía de San Quintín near San Quintín, Baja California.They are commonly found in the upper intertidal zone on mussels, rocks and pier pilings.
Paraconcavus pacificus, the red-striped acorn barnacle, is a species of balanid barnacle known from sandy tidal habitats of the outer northeast Pacific coast from Baja California north to Monterey Bay. The barnacle reaches 35 mm in diameter, has pink longitudinal stripes on white plates, and can be distinguished from other large, pink-striped barnacles in its range (e.g. Amphibalanus amphitrite) by the longitudinal stripes along the growth rings of its plates. The barnacle attaches itself to many different types of hard substrates, but also prefers the shells of other organisms, particularly the sand dollar.
Food: phytoplankton, zooplankton and detritus.
