A large moray eel at East Coast Park! Ivan found this rather pale, but very much alive Estuarine moray eel.
Earlier on, Ivan found another moray eel. It too was rather pale but very much alive. These are the largest Estuarine moray eels (Gymnothorax tile) I've seen!
on 26 May. I last visited this shore in July 2010 when the shore was clean, but was a little quiet. But Ivan visited on 22 Apr (facebook) and saw a shore that seemed a little more lively. It was also somewhat lively when I last visited the shore in May 2011.
One of my favourite animals seen before the oil spill are pretty Button snails (Umbonium vestiarum). As I arrived, I noticed piles of tiny shells of dead Button
snails on the high shore, a promising sign. Elsewhere, there were piles of other kinds of tiny snails.
Olive snail (Family Olividae)! My first time encountering this behaviour in an olive
snail. I saw another olive snail nearby. So the return of the button snails probably helped replenish the population of predatory snails too.
Ball moon snails (Polinices didyma). These animals can inflate
the body to be much larger than the shell. As they plough through the
sand, the body also protects the tiny pair of tentacles and little
siphon which sticks out above the sand.
with pretty lilac lines, which I have yet to identify. I
finally managed to get better photos of these tiny snails. They seem to
have pretty white spots on the foot!
Frog snail (Bufonaria sp.). I rarely see this snail alive. This shell was occupied by a hermit crab.
Cake sand dollars (Arachnoides placenta) on the shore. But most were small.
Tidal hermit crabs (Diogenes sp.) that live in the button snails,
there were also some larger Tidal hermit crabs, and several small Striped hermit crabs (Clibanarius infraspinatus).
Moon crabs (Family Matutidae) on the shore from very very tiny ones to medium sized ones.
Flower crabs (Portunus pelagicus) from those tinier than a Button snail to small ones swimming in the water. On the high shore we saw several burrows and one live Ghost crab (Ocypode cerathophthalmus).
Penaeid shrimps (Family Penaeidae). They were jumping out of the shallow water every now and then.
Whitings (Family Sillagenidae) in the shallow water. I also came across three gobies (Family Gobiidae) and Ivan saw some tiny flatfishes.
Sand bubbler crabs (Scopimera sp.). The sand balls were as big as the crab and there were many sand balls. Wow, these crabs sure move a lot of of sand relative to their size.
sponges, and other
colourful encrusting life. Also Mermaid's fan seaweed (Padina sp.), Sea lettuce (Ulva sp.) and
lower down in the water, on hard surfaces, clumps of Agar-agar seaweed (Gracilaria sp.).
Purple climbing crab (Metopograpsus sp.) and two Sally-lightfoot crabs (Grapsus albolineatus). These fast moving crabs are quick to scuttle away. Ivan saw another crab which might have been the Spotted-belly forceps crab (Ozius guttatus).
Cloister blenny (Omobranchus elongatus) that we had seen earlier also at East Coast Park? We carefully put back the stones to avoid squashing animals.
triton snails (Family Ranellidae) laying neat circles of egg masses.
Javan limpets (Siphonaria javanica) with lots
of coils of jelly nearby. Are these their egg masses? Wow, my first time seeing them!
