Lithophyllon undulatum, a mushroom coral!
The invaluable paper that I poured over is: Danwei Huang, Karenne P. P. Tun, L. M Chou and Peter A. Todd. 30 Dec 2009. An inventory of zooxanthellate sclerectinian corals in Singapore including 33 new records (pdf). Raffles Bulletin of Zoology Supplement No. 22: 69-80.
I also laboured over Veron's amazing coral bible: Corals of the World (Thanks to Siti for the hardcopy), which is now also available online!
From all this squinty-eyed study I think this pretty hard coral might be Pachyseris rugosa. The common name is Castle coral, which is quite appropriate as the colony does look like a fantastical castle! We saw quite a few on Terumbu Bemban and it seems I've seen them on some of our other shores too. Previously, I lumped them all together with Ringed plate corals, which I now think are Pachyseris speciosa.
Feather mushroom coral which is also appropriate as the neat parallel lines on the oval coral does make it resemble a feather.
Bracket mushroom corals are Podabacia sp., and also that some Fungia species are Circular mushroom corals while others, like the one below are Oval mushroom corals.
Pseudosiderastrea tayami which belongs to Family Siderastreidae
eBivalvia on EOL's Life Desk kindly stopped by the fact sheets and helped identify some of the Venus clams that I've been seeing. Thanks to his very useful tips, I've sorted them out a little better (I hope). These more rounded ones that are often seen on our Northern shores are probably Gafrarium divaricatum.

on shores like East Coast Park!

Please do let me know if I got any of the identifications wrong!
As usual, I'm way behind on the fact sheets. There were lots of other interesting sightings. Some are first entries to the wild fact sheets for the location. Others are interesting behaviours observed for the first time. There are also lots of interesting video clips! These photos and video clips have been updated on the wild fact sheets. Thanks to all the team members who shared their findings online. Visit their sites for more stories and photos!
