Bathochordaeus charon and its ‘house’ in Monterey Bay: giant larvaceans use their oikoplastic cells to secrete complex filters or ‘houses’ that allow them to concentrate and feed on particles; a ‘house’ consists of a large, diaphanous outer structure as well as a smaller, more convoluted and bi-lobed inner structure that functions as a filter; together these serve to concentrate appropriately-sized food particles from the surrounding water; in situ, larvaceans in the genus Bathochordaeus are often visible from several meters away because their houses may span a meter in longest dimension.
