Courtship behaviour of saltwater crocodiles

Video Synopsis:
In the first video (slow motion), the female is observed to have an elevated head posture (to initiate copulation or signal readiness to mate?). In the second video, after Tailless approaches a female (filmed on a different day; slowed down 5x) he performs a courtship bellow. Tailless is then observed to perform underwater copulation with the female crocodile (the female's tail can be observed at least twice during copulation).
