特徴

産地:Capitulum mitella occurs in the South China Sea and the East China Sea. It is found attached to rocks in the lower part of the intertidal zone in areas with strong currents. It typically occurs crowded with others in cracks and grooves on otherwise smooth rocky surfaces. The barnacle Tetraclita squamosa often occurs in the same locations and grows alongside it, and the primitive barnacle Ibla cumingi may grow in between or on the larger capitulum plates.
特徴:Capitulum mitella has a short leathery stalk or peduncle supporting an upper region or capitulum, the whole being up to 5 cm (2 in) long. The peduncle is muscular and contractile and its surface is covered with fine scales. The capitulum is protected by eight large, sheathing scales and a ring of about twenty tiny scales surround the joint of capitulum and peduncle. Inside these scales is a cavity containing the head and thorax of the animal and its appendages.
