The last dive of the trip was absolutely amazing. I'm always on the lookout for octopus but sightings are rare in New Zealand and my expectations are low. So as I was looking under every ledge and every crevasse, I was excited to find an octopus tucked away under a ledge.
I probably spent a good five minutes with this octopus. It wasn't very active and stayed put while I observed it.
As I left the area, I made a mental note of where it was as I wanted to stop by again on my way back. When I returned, I was astounded to find another octopus in the area!
Shortly after, the second octopus moved out from under the ledge and changed shape and colour to match the reef.
Then I noticed that the second octopus was reaching back to the first octopus underneath the ledge. That's when I realised what was happening. They were mating.
"When octopuses reproduce, the male uses a specialised arm called a hectocotylus to transfer spermatophores (packets of sperm) from the terminal organ of the reproductive tract (the cephalopod "penis") into the female's mantle cavity." Read Octopus Reproduction.
I immediately switched to video to record this tender moment.
I don't know what the likelihood of a recreational diver observing octopi mating is but I suspect it's highly unlikely. I was very fortunate to witness this and have the air to casually and carefully get the pictures and video. It was truly an amazing encounter.
