Anatomy Study to the Reproductive System in the Female Scorpions Androctonus Crassicauda

Abstract

Objectives: This study has investigated the anatomy of the reproductive system in the female scorpion Androctonus Crassicauda. Methods: Eight adult females were collected and dissected to investigate the structure and function of their reproductive organs. The adults female of scorpion Androctonus Crassicauda belonging to family Buthidae and the females of scorpion Androctonus Crassicauda were collected from provinces Baghdad and Wasit. Measurements of various body parts were taken, and the internal anatomy was examined under a microscope. Results: In general studies showed the female of scorpions have the ovariuterus consists of a reticular net are longitudinal and transverse ovarian tubes extend from third to seventh mesosomal segments, longitudinal ovarian tubes connected either by transverse ovarian tubes, but in the Buthidae family have an eight-celled reticular ovariuterus, that is five transverse ovarian tubes and the female Androctonus Crassicauda do not have five transverse tubes only the anterior and posterior forming a two-celled ovariuterus, and they have reproductive organs include ovaries, uterus, vagina. These results showed that female Androctonus Crassicauda has a simplified ovariuterus compared to other scorpions in the Buthidae family. It has only two cells because all the distal anastomosis are absent, the oocytes are contained in follicles directly in contact with the ovariuterus, Conclusions: This unique anatomy may be related to the reproductive strategies of this particular species, all scorpion juveniles derive some nutrients directly from females during development. The functions of these organs are involved in fertility, conception, pregnancy, and childbirth. The reproductive organs also have a significant influence on other aspects of health. The major function of the reproductive system in scorpions is to ensure the survival of the species and there are many systems in the body like the endocrine and urinary systems, which work to maintain homeostasis for survival. Reproduction plays a role in evolution as it creates variations via genetic recombination, therefore it is needed to have detailed study and experiments for the understanding of anatomy of the reproductive system in the Female Scorpions.
