Statistical considerations about the metric values of the corporeal segments of the reproductive system of escargots of the species Achatina fulica and Achatina monochromatica

Abstract

The objective of this work was to perform a metric study of the reproductive system of the species Achantina fulica and Achatina monochromatica , establishing comparative parameters between both, to improve the knowledge of the species. After the selective process, weighting and measures of the shell, the specimens were frozen in freezer to -2(0)C for approximately 10min as a sacrificing form. For each segments the measures proceeded after the retrieval of the reproductive system through a longitudinal incision. The statistical analysis showed that, in spite of the specimens be maintained under the same environmental and alimentary conditions and submitted to the same selection type, variations happened in the development and size of the reproductive organs. The morphologic aspect of the reproductive system in both species differs macroscopically in several segments; however, the disposition and the location of those segments are identical.
