Octopus copulation

Postby Raewyn » Fri Jan 01, 2021 9:30 am

Happy New Year!

We had our usual pre Christmas trip to Kapowairua/Spirit's Bay. I saw a total of 6 octopuses in the rock pools which is the most for some time. Most were single sightings and the one I did see three times told me to "go away" so I didn't get any ongoing engagement this time. Then, on the last day, from above I saw an octopus at the bottom of one of the deeper pools, sitting out from the edges which was unusual. I dropped a cracked oyster for it but it didn't move. I put the GoPro in and it didn't move. I wondered if it was dead but its colour looked OK apart from one arm being different. So I wondered if it was injured, thought it best to leave it alone, and went on my way.

But... when I downloaded the GoPro photos this was what I saw. A second octopus that was just out of view from above and they appear to be copulating. Since it's something a bit different I thought others might be interested.

What an amazing thing to see! Male cephalopods have a modified arm, called a hectocotylus, which they use to pass spermatophores to the females, definitely looks like that's what's going on here.

Thanks. Octopuses are amazing animals and this was certainly an unusual encounter.

That is a neat thing to see.
