Slugfest at Sentosa

The clumps of stringy green seaweed (Bryopsis sp.?) are a great place to find tiny juvenile creatures (Though it helps to bring a few super spotters with seeming bionic eyes along...). Chay Hoon and Ron came yesterday and they assaulted Ria's poor camera with a whole host of tiny creatures, all of which were <1cm (see algae for size comparison)! Amazing stuff.


Tiny juvenile Jorunna funebris, especially cute when they are tiny.


The orange-spotted Gymnodoris sp. resembled a tiny lemon, sans the help of close-up filters and digital enhancement.


A tiny unknown Armina beside the Jorunna funebris, and if you look really carefully, a REALLY tiny Aeolid nudibranch beside it. We've seen bigger ones before, crawling on a similarly-coloured sea squirt.


Going down the size scale, here's one that was barely 3mm long. Picture was taken after numerous attempts with a stereomicroscope and my normal camera. No idea what it might be. I like to think of it as the green porcupine nudibranch because when it moves (and quite quickly at that), the swaying extensions on its back remind me of the quills of a porcupine.


The only bigger nudibranch spotted by the rest of us mere mortals with normal vision - a beautiful Discodoris boholiensis. I thought it was a flatworm, curled up around the seaweed, but closer inspection revealed rhinopores and later gills. Really funky-looking fella, underside looks rather like that of an onch.
