Abstract
The penis of each individual is inserted into the vaginal pocket of the mate, so that sperm are deposited directly into the dorsal chamber of the seminal bursa. Impregnation is, in some cases, at least, reciprocal. The entire process lasts only 1-1 1/2 minutes. There is no evidence of the occurrence of hypodermic impregnation in this species, as described by Gardiner for Polychoerus caudatus.This publication has 1 reference indexed in Scilit:
