马氏正钳蝎的形态和结构特征

马氏正钳蝎(Mesobuthus martensii)又称东亚钳蝎,是中国最常见的蝎种。针对该蝎种系统性研究相对薄弱的现状,本文通过扫描电子显微镜、体视显微镜、解剖学等手段对马氏正钳蝎的形态结构进行了研究,全面系统地描述了马氏正钳蝎的外部形态和内部结构特征,完善了该蝎种生物学特征的基础数据,特别是对其呼吸系统、生殖系统及毒腺的结构进行了详细的研究,观察和分析了马氏正钳蝎的螯肢、眼睛、步足及听毛、生殖孔、栉齿感受器、书肺、毒腺等结构特征及相关功能,探讨了不同视觉蛋白的差异性表达、感光功能差异性与蝎子生存进化的相关性。

The Morphological and Structural Characteristics of Mesobuthus martensii

The Mesobuthus martensii is widely distributed in China.It is recorded by traditional Chinese Pharmacopoeia as a famous medicine.According to the situation in which the systematic study on this scorpion was weak,the morphology and structure of the scorpion species were studied in-depth level by this study.In this paper,we used scanning electron microscope,stereo microscope and anatomical method to systematically describe the morphology and structure features of M..martensii,and improve the basic data of the scorpion biological characteristics,especially for the structure of the respiratory system,reproductive system and venom:1.the structure characteristics of median and lateral eyes,chelicerae,pedipalps and legs including auditory hair on legs (Fig.1-4);2.the morphological structure and function of stemite region including pectines with sensilla on it (Fig.5-6);3.distribution and morphology of book lung in situ and its anatomical structure of lung lamellae (Fig.7);4.the structure in details of venom vesicle and aculeus showing dissection of venom gland and the canals (Fig.8).We explored the relationship between the different expression of different visual proteins,the different function of photoreceptor in scorpion evolution And investigated the sensing function of the tail in mating and predation defense.
