intromission

In contrast, the modern visual theory is called “intromission,” and is based on the notion that vision results from light entering the eyes.

We found a way to inflate them so they would be the most close mimic of what a real intromission would look like.

With insufficient stiffness, intromission will not happen and the genes of the male will fail to make it into the next generation.

At times the male approached the female from the rear and slightly to the side, biting the dorsal part of her neck and simultaneously attempting to effect intromission.

Possibly intromission can be maintained in this position even when the female is attempting to escape.
