（4）瓣的形状不随盐度变化。似有相同的趋势，形态变化在阿萨拉斯沃茨，但阈值不同。一个培养实验补充了现场观察。我们选了C。torosa从南波罗的海沿岸的一个网站，并保持它在实验室中的550天，覆盖在0.5和13 psu之间的盐度范围在几个系列的微观世界。标本孵化和发展，在我们的微观世界，并进行了研究的大小变化，结瘤，筛孔，和形状的变化。沿着盐度梯度的大小变化显示出与野外相同的模式，但明显矮化标本。与现场数据的阶梯模式相反，在我们的培养物中可以看到节瓣比例与盐度的明显线性相关性：
and (4) no salinity dependant shape variation of valves. There seem to be the same tendencies to morphological changes in athalassic waters but the thresholds are different. A culture experiment complimented the field observations. We took C. torosa from a site on the southern Baltic Sea coast and kept it for 550 days in the lab covering a salinity range of between 0.5 and 13 psu in several series of microcosms. The specimens hatched and developed in our microcosms and were studied for size variation, noding, sieve pores, and shape variation. The size variation along the salinity gradient shows the same pattern as in the field but are clearly dwarfed specimens. In contrast to the staircase pattern of field data a clear linear correlation of noded valve proportion to salinity is visible in our cultures:
