The Red-striped Acorn Barnacle[2] (Paraconcavus pacificus) is a species of balanid barnacle known from subtidal sandy habitats of the outer northeastern Pacific coast, from Baja California north to Monterey Bay[3]. It grows to 35 mm in diameter, with pink longitudinal stripes over white plates, and can be distinguished from other large, pink-striped barnacles in its range (e.g. Amphibalanus amphitrite) by the longitudinal striations across the growth rings of its plates[3]. While it will attach to many different kinds of hard substrate, it shows a preference for attaching the shells of other organisms, particularly sand dollars[3].
