balanus

Balanus is a genus of barnacles in the family Balanidae of the subphylum Crustacea.Balanus amphitrite is small about 1.5 cm diameter. The color is whitish with purple or brown longitudinal stripes. Surface of test plates are longitudinally ribbed. The interlocking tergum and scutum, the paired structures which cover the animal inside are as pictured below.A similar species, Balanus reticulatus Utinomi, commonly occurs with B. amphitrite. It also has longitudinal purple or brown stripes, but these stripes are intersected by horizontal grooves, giving the surface of the test plates a rough reticulated striation, unlike B. amphitrite. It can also be distinguished by examination of the tergum and scutum. Note the more sharply pointed apex of the tergum and the elongated and narrower tergum spur of B. reticulatus.
