The article in Nature is entitled: Female insect uses spiky penis to take charge. The opening sentence:
In desolate caves throughout Brazil live insects that copulate for days, the female's penetrating erectile organ sticking fast in a reluctant male's genital chamber until he offers a gift of nutritious semen.If that sentence leaves you confused, see the link. And if you think we are posting a picture of that, then you would be wrong. We have.... NOTHING.
