One of the most interesting finds was to come across Tomato anemonefishes in a Bubble tip anemone (which was sadly still bleaching). Usually the largest anemonefish in the group is the female and the next largest is the functioning male (although he is often less than half her size). If the female is removed, the next largest male changes sex and becomes the dominant male. Small anemonefishes are not necessarily younger, just lower in the "pecking order". It is believed they remain small because of the constant harassment by the dominant pair.
Among the sea anemones we saw were Fire anemones, many Giant carpet anemones (none with anemonefishes), some Frilly sea anemones, and Bubble tip anemones. Nick also came across Haddon's carpet anemones. Aside from the one Bubble tip anemone with anemonefishes, all the other sea anemones I saw were not bleaching.

Cauliflower coral, Pebble coral, Ridged plate coral, Brain coral and Carnation coral.
Acropora corals. Chay Hoon also saw a Sunflower mushroom coral! I saw one large Mole mushroom coral but didn't see any Circular mushroom corals.
leathery soft corals of various kinds.
Phyllidella nigra. Pei Yan saw some other nudibranchs. Chay Hoon saw several different kinds of mantis shrimps! Chay Hoon found a new Fluted giant clam but we still couldn't find the Fluted giant clams that we saw on our trip in Apr 2016.
Cryptic sea stars. I couldn't find any sea stars today.

There is a sprinkling of cropped Tape seagrass, and on the higher shore, patches of Spoon seagrass and Needle seagrass.
Tape seagrasses stick out of the water.
Just as Changi Airport and Changi Prison are not the same even though they are near one another and share a name, Pulau Semakau is NOT the same as the Semakau Landfill. The Landfill was created by destroying all of Pulau Saking, and about half of the original Pulau Semakau by building a very long seawall. Fortunately, the landfill was constructed and is managed in such a way that the original mangroves, seagrass meadows and reefs on Pulau Semakau were allowed to remain. The northern shore of Pulau Semakau is near the petrochemical plants on Pulau Bukom.
Phase 2 of the Landfill was just recently launched. This involved closing the gap of the seawall on the Semakau Landfill, forming one big pool where incinerated ash will be dumped. NEA worked to limit the damage to natural shores during the construction work for this expansion of the landfill.
