What is the mating ritual of the whale?

Male bottlenose dolphins will join together and approach a group of females, attempting to sway a female out of her group. If the female is unimpressed, she will try to escape. The males will then surround her, going as far as slapping her with their fins and biting her to keep the female from escaping.

Male Amazon River Dolphins have a gentler approach. They will take a stick, rock, or lump of water weed in their mouth and swim to the surface, rising out of the water and twisting on their axis. One male was even reported displaying a turtle. Observations found that the biggest males carry the heaviest objects, thus fathering the most offspring.
