[Tissue structure observation of internal organs and skin of Whitmania pigra]

Through observation of the tissue structures of internal organs and skin of Whitmania pigra, to provide basic method for identification of W. pigra and research of its physiological functions.

This experiment adopted the W. pigras as the material and carried on dissection observing,and W. pigra's cavity, swallow, esophagus, crop, bowel, rectum, parasomal sac stomach, testicle, seminal vesicle, vasa deferentia duct, ejaculatory ball, prostate gland and skin was observed by the method of the paraffin organization slice and microphotography.

The structures and functions of the skin and the organ of the digestive and reproductive system, as well as the types and distributions of the mucous cells were acquired,which provided abasis for further study on the living behaviour, propagating behaviour and breeding environment of W. pigra.
