软甲介纲甲壳类动物，如螃蟹，用一排被称为嗅器的嗅觉感受器在水中摆动触角来感知气味。螃蟹的划水动作包括一个快速的下划动作，在下划动作中，尾须横向偏转（张开），以及一个较慢的反向回划动作，在回划动作中，尾须聚集在一起。这种运动导致水被冲到内部，然后被保持在两个感觉器官之间，将气味分子传递到嗅觉受体。虽然这种气味采样方法依赖于一个狭窄的范围内的速度，大小，和特定的安排的aesthetascs，大多数螃蟹显着改变这些在个体发育。在这项研究中，形态计量学的触觉，阵列，触角和闪烁的俄勒冈州海岸蟹，Hemigrapsus oregonensis（十足目：Brachyura）的运动学，检查，以确定其比例关系在个体发育。阵列和天线的形态测量比等距线预测的要慢。幼蟹的嗅器比成年蟹的嗅器张开得更远，这可能是由于嗅器表皮在生长过程中材料性质的变化。这些结果表明，不成比例的增长和变化的触觉splay在轻弹将介导的大小变化，由于增长，否则会导致功能丧失。
Malacostracan crustaceans such as crabs flick antennae with arrays of olfactory sensilla called aesthetascs through the water to sense odors. Flicking by crabs consists of a quick downstroke, in which aesthetascs are deflected laterally (splayed), and a slower, reversed return stroke, in which aesthetascs clump together. This motion causes water to be flushed within and then held in between aesthetascs to deliver odor molecules to olfactory receptors. Although this odor sampling method relies on a narrow range of speeds, sizes, and specific arrangements of aesthetascs, most crabs dramatically change these during ontogeny. In this study, the morphometrics of the aesthetascs, array, and antennae and the flicking kinematics of the Oregon shore crab, Hemigrapsus oregonensis (Decapoda: Brachyura), are examined to determine their scaling relationships during ontogeny. The morphometrics of the array and antennae increase more slowly than would be predicted by isometry. Juvenile crabs' aesthetascs splay relatively further apart than adults, likely due to changing material properties of aesthetasc cuticle during growth. These results suggest that disproportionate growth and altered aesthetasc splay during flicking will mediate the size changes due to growth that would otherwise lead to a loss of function.
