my second male is actively persuing the two newts in amplexus, in an attempt to join the mating. The male in the pair is maintaining distance, yet I have seen the third attach himself to the females underside, thus 'eliminating' the requirement ("until he is done amplexing, and guide the female, if she is receptive, over the spermatazoe") of a receptive female.
Only in the event of a three newt group have i witnessed the female directly receiving his sperm. However, it is him I see trying to swim away from the additional advancing male, not her, and they are frequently engaging in amplexus without my knowledge.
