摘要

甲壳类嗅觉感受器的形态变化是相当大的,似乎包括美学和雄性特异性感受器。迄今为止,在一些非十足动物群体中已经描述了雄性特异性感受器,而十足动物嗅觉系统的两性二态性在形态学上通常不太突出。与非十足动物相比,十足动物的每个感觉器官通常有更多的感觉细胞。审美和雄性特有的感受器排列成不同密度的阵列。感觉器排列的差异可能反映了不同的刺激获取行为。

Olfactory sensilla in crustaceans: Morphology, sexual dimorphism, and distribution patterns

The morphological variation of crustacean olfactory sensilla is considerable, and appears to comprise both aesthetascs and male-specific sensilla. Male-specific sensilla have hitherto been described in some non-decapod groups, whereas the sexual dimorphism of the olfactory system of decapods is usually less prominent morphologically. The decapods usually have a larger number of sensory cells per aesthetasc sensillum than non-decapods. The aesthetascs and male-specific sensilla are arranged in arrays of varying density. Differences in the arrangement of sensilla probably reflect diverse stimulus acquisition behaviour.
