We met many molluscs on Cyrene this morning. Including the delightful China moon snail!
Some of the moon snails were 'carrying' little snails on the back of the foot! I saw two carrying Button snail shells! But we couldn't find any live Button snails! This is the first time I've seen so many China moon snails (Natica onca) out and about. First spotted by Mei Lin last year, so far, I've only seen them on Cyrene. They are very pretty with a decorative shell and gaudy foot. The operculum (door that closes the shell opening) is white and shelly with grooves.
Grey bonnet snails (Phalium glaucum)! They were busy feeding on the many large Cake sand dollars (Arachnoides placenta) found on the clean sand bars here.
Japanese bonnet snail (Semicassis bisulcatum). So far, I've only commonly seen these two snails also at Changi. In many ways, Cyrene is like the Chek Jawa of the South with many animals found here that are only usually found on our Northern shores.
Egg-white moon snail (Polinices albumen) with its broad white body expanded. It's another snail that I've only also seen at Changi.
Olivia miniacea and so far, I've only seen them on Cyrene.
Discodoris lilacina which I've so far only seen on Chek Jawa and Pulau Sekudu. Chay Hoon and the rest of the team found lots more nudibranchs! Kok Sheng saw a lot of Forskal's sidegill slugs (Pleurobranchus forskali) too!
Starry flatworms (Pseudobiceros stellae), and I think the one in the lower row is also a Starry flatworm although it looks rather different.
Common sea stars (Archaster typicus). They were very much smaller than the usual ones we see.
White sea urchins (Salmacis sp) which are common in the North but not often seen on our Southern shores. On Cyrene, these come in various shades of white, with spines that might be white, greenish or pinkish.
Long-spined black sea urchin (Diadema sp.), its spines are still banded.
heart urchin (Lovenia elongata)! These animals are efficient burrowers (as demonstrated by this animal as we tried to photograph it) and usually seldom encountered above ground.
Pentaceraster sea star (Pentaceraster mammilatus). It's a young one and seems to be doing fine. We also came across a large Remarkable sea cucumber (Holothuria notabilis) buried in the sand and I saw some small Garlic bread sea cucumbers (Holothuria scabra) in the seagrasses and several Long black sea cucumbers (Holothuria leucospilota) in the rubbly area.
Swimming anemone (Boloceroides mcmurrichi). When I gently waved it off its perch, it shed its tentacles and it did swim. But it was pinkish with spots! Quite different from the Swimming anemones I usually see, which have banded tentacles.
Haddon's carpet anemone (Stichodactyla haddoni) and two Snaky sea anemones (Macrodactyla doreensis). I saw a tiny Giant carpet anemone (Stichodactyla gigantea) and it was constantly moving its tiny tentacles, a distinctive feature of this anemone!
Needle seagrass (Halodule sp.) can be very broad or very narrow. But they have the same 'bat-ear' tips!
Sickle seagrass (Thalassia hemprichi) and Serrated ribbon seagrass (Cymodocea serrulata).
Oval sea grapes (Caulerpa racemosa) had some paler portions surrounded by a greenish 'haze'. Is this seaweed 'spawning'? So much more to learn about our shores!
TeamSeagrass makes its next monitoring trip to Cyrene. I didn't have a chance to see the reefs today.
There are still many many Knobbly sea stars (Protoreaster nodosus) on Cyrene, both small and large.
massive flaring on Jurong Island. Apparently dubbed the Eye of Sauron by some. The height of the flame seems almost as tall as the chimney!
Dredging near Cyrene has been extended multiple times and as of now scheduled to go on until October. These are some of the pressures on Cyrene as it lies in the middle of the industrial triangle.
Slender lined shrimp goby (Cryptocentrus leptocephalus), apparently my first sighting of this fish on Cyrene. Hurray!
More about Cyrene.
