食肉动物进化中最大的生态转变之一是从陆地生活方式向水生生活方式的转变，这推动了头骨和其他骨骼结构的形态多样性。在本文中，我们调查这些生活方式和胡须形态之间的关联。然而，比较一系列物种的晶须形态是具有挑战性的，因为晶须的数量和它们在mystyrene垫上的位置在物种之间是不同的。此外，每根晶须将处于不同的生长阶段，并且可能由于磨损而受到损坏。确定一种方法来容易地捕获晶须形态在少量的晶须样品将是有益的。在这里，我们描述了来自赤狐，欧洲水獭和灰海豹二维扫描的胡须形态的个体和物种差异。长的尾须的比较最清楚地显示了种间差异。我们继续描述全球晶须形状的24种食肉动物，使用线性近似的曲率和锥度，以及传统的形态测量方法。我们还定性检查表面纹理，或存在的规模，使用扫描电子显微镜照片。我们发现，总晶须形状是高度保守的，晶须曲率和锥度服从简单的线性关系与长度。然而，晶须基部半径、长度甚至曲率的测量可以在物种和基底偏好之间变化。具体来说，我们样本中的水生物种有更厚，更短的胡须，更光滑，鳞片比陆生物种少。我们认为，这些较厚的晶须可能更硬，能够保持其形状和位置在水下传感，但更硬也可能会增加磨损。
One of the largest ecological transitions in carnivoran evolution was the shift from terrestrial to aquatic lifestyles, which has driven morphological diversity in skulls and other skeletal structures. In this paper, we investigate the association between those lifestyles and whisker morphology. However, comparing whisker morphology over a range of species is challenging since the number of whiskers and their positions on the mystacial pads vary between species. Also, each whisker will be at a different stage of growth and may have incurred damage due to wear and tear. Identifying a way to easily capture whisker morphology in a small number of whisker samples would be beneficial. Here, we describe individual and species variation in whisker morphology from two‐dimensional scans in red fox, European otter and grey seal. A comparison of long, caudal whiskers shows inter‐species differences most clearly. We go on to describe global whisker shape in 24 species of carnivorans, using linear approximations of curvature and taper, as well as traditional morphometric methods. We also qualitatively examine surface texture, or the presence of scales, using scanning electron micrographs. We show that gross whisker shape is highly conserved, with whisker curvature and taper obeying simple linear relationships with length. However, measures of whisker base radius, length, and maybe even curvature, can vary between species and substrate preferences. Specifically, the aquatic species in our sample have thicker, shorter whiskers that are smoother, with less scales present than those of terrestrial species. We suggest that these thicker whiskers may be stiffer and able to maintain their shape and position during underwater sensing, but being stiffer may also increase wear.
