| 摘 要： | 本文研究了舟山沿海两种笠藤壶（日本笠藤壶Ｔｅｔｒａｃｌｉｔａｊａｐｏｎｉｃａ、鳞笠藤壶Ｔ．ｓｑｕａｍｏｓａｓｑｕａｍｏｓａ）个体的形态变异，分析了壳板形态与生境、潮区、年龄之间的关系以及壳板形态的种间差别。壳口面积与基底面积之比值（Ｓａ／ＳＡ）在各年龄组间变化较小，而壳口面积与个体容积之比值（Ｓａ／Ｖ）随着藤壶年龄增加而减小，藤壶个体亦随年龄增加由矮圆锥形变陡。盖板各测值之比值在不同年龄组间变化不大，受环境影响较小，可以作为分类鉴定的依据。

| Abstract: | The morphological variation of two species of barnacle (Tetraclita japonica, T.squamosa squamosa) along the shore of Zhoushan Islands was studied. The relationships between the shell shape of barnacle and its ecological nich, tide zone and age, and the difference of shell plate between two species were discussed. The ratio of the area of aperture to shell bottom varies little among age groups, while the ratio of the area of aperture to the individual volume (S a/V ) decreases with age and the external appearance of the barnacles changes gradually from low conical to steep conical with age. The ratios between variates of the scuta and terga of the barnacle are almost constant among age groups and are affected little by environment. |
