William Drumm, a 31-year-old photographer, and filmmaker, from Denver, Colorado, captured the pair of spinner dolphins in slow motion as they get cozy off the coast of Hawaii, in August, last year.
He said: “The video shows the pair of spinner dolphins appearing to mate, and getting heckled by other dolphins during the process.
“The male appears to hit the female several times with its snout while attempting to mate with her.
“Spinner dolphins are notoriously sexual, often mating with many individuals in their pod.
“Because of this, the parents aren’t always sure who the offspring belongs to, so a communal style of raising young is used.”
“Watching dolphins never fails to amaze me.”
