Back again to survey oil-slicked Tanah Merah, today doing the stretch near the Ferry Terminal. A night trip usually means more fishy sightings and I wasn't disappointed.
I also saw a cuttlefish (Family Sepiidae) today!
Chocolate hind (Cephalopolis boenak) on the shore. Also many Bengal sergeants (Abudefduf bengalensis).
Hollow-cheeked stonefish (Synanceia horrida) is so well camouflaged, there are probably others that I didn't see.
April 2012, filefishes (Family Monacanthidae) were abundant, although they are very well camouflaged.
cardinalfishes (Family Apogonidae) and the Black cardinalfish (Apogon melas), White spotted rabbitfishes (Siganus canaliculatus), halfbeaks (Family Hemiramphidae).There were also many damselfishes (Family Pomacentridae), Painted scorpionfishes (Parascorpaena picta), lots of gobies (Family Gobiidae) of all kinds.
Tongue mushroom coral (Herpolitha limax)!
Anemone corals (Goniopora sp.), Circular mushroom corals (Family Fungiidae) and small Disk coral (Turbinaria sp.).
Favid corals (Family Faviidae) in all colours and patterns.
Pore corals (Porites sp.), which formed the largest colonies on this shore. Most were not bleaching although some had dead portions and others were rather orange.
Button zoanthids or colonial anemones (Zoanthus sp.).
Swimming anemone (Boloceroides mcmurrichi) and several Frilly sea anemones (Phymanthus sp.).
Stone crabs (Myomenippe hardwickii) and Red egg crabs (Atergatis integerrimus). Also one Velcro crab (Camposcia retusa) and the Sea toad spider crab (Scizophrys sp.). As usual, there were many small Swimming crabs (Family Portunidae) and some Spotted moon crabs (Ashtoret lunaris).
Spoon seagrass (Halophila ovalis) which I first noticed in Apr 2012 is still there, covering quite a large area. The Spoon seagrasses disappeared even before the oil spill, so it's good to see them back.
Sickle seagrass (Thalassia hemprichii) is also growing larger and seem to be doing alright. The blades are no longer 'chomped' at the tips.
Tape seagrass (Enhalus acoroides) and they seem ok, although the leaf tips are still burnt.
Smooth ribbon seagrass (Cymodocea rotundata) have grown enormously. Both have reached the rock wall. The patches are still studded with small Haddon's carpet anemones (Stichodactyla haddoni). Sadly, also litter. I couldn't find any anemone shrimps today.
Pink moon snail (Natica zonalis), and lots and lots of Dubious nerite (Clithon oualaniensis) crawling on the leaf blades.
Common sea stars (Archaster typicus), but it's hard to spot them during a night trip, especially alone. Also no landscape photos as the trip ended before sunrise.
Scum still forms on much of the water surface, more obvious near the rocks with the outgoing tide.

This shore is where we saw this Siemens water project during a trip a few weeks ago.
their explanation of the project and my additional questions to their reply.
