Yesterday, we were looking more to the big picture, with imagery from Stingray City in Grand Cayman. Today’s pic is back to something quite small, and I think a bit unusual – a free swimming flatworm, that I captured in Ambon Harbour in Indonesia – home of some pretty bodacious muck diving.
Flatworms, which are cousins of nudibranchs, are cool little critters, and there seems to be a lot of them. This one is (I think) some sort of Pseudobiceros. A bit hard to tell, as these things are usually creeping across the reef when we see them, not curled up like this in swimming contortions. I can’t find a positive match in my id book.
This one had launched itself and was swimming up off the reef, in the water column. It was spotted during a shore night dive, and I will admit to quite a bit of luck in actually getting it in focus – a devilish proposition with a macro lens in manual focus mode in black water.
If I recall correctly, it was about 2 inches long.
