How about I start us off this month? And not an easy challenge, Elena!
I tried a few times with harp and whip corals – solid choices for leading lines, but I was not satisfied with the results. They were lines, but not really leading anywhere.
Instead, I will go with the undulating lines of those two flatworms, what I suspect are brown-stripe flatworms (Pseudobiceros sp. 2). They are a common fixture in our Singapore waters, and these two were very busy – it was mesmerising to watch them move, and their body margins pulsating and gravitating towards each other.
And I was lucky to stick around long enough to see how those lines led both flatworms to the ultimate mating behaviour: “penis fencing”. If you’re not familiar with it, here is the great Dr David Attenborough explaining:
