At first I thought two males were simply facing off but on closer inspection the plot thickened.

First I noticed a diminutive female beneath one male, now thinking he defended his claim. Then I realised a second female lay protected beneath the second male. So it was clear now that both males had their prize mates.

In the distance, on all flanks, challenging suitors lurked patiently waiting their chance.

At last the scene beneath my cuttlefish eye made perfect sense.
