Terumbu Pempang Laut is one of our largest submerged reefs and located near industrial islands such as Jurong Island and Pulau Bukom.
Coral are colonies of tiny animals called polyps. Each polyp lives inside a little hard skeleton. The huge colony is made up of the skeletons of countless polyps. The polyps of all reef-building hard corals harbour microscopic, single-celled algae (called zooxanthellae). The polyp provides the zooxanthellae with shelter and minerals. The zooxanthellae carry out photosynthesis inside the polyp and share the food produced with the polyp. Corals generally have white colour skeletons, which is believed to assist in photosynthesis by reflecting light onto the zooxanthellae.
May 2015. Many Merulinid corals had bleaching patches, some with patches of recently dead tissue, these range from 20-60% of the colony.
Pore corals and most were not bleaching. But many had also recently dead patches.
Cauliflower corals that were bleaching with patches that recently died. I saw a few Anemone corals and Small goniopora corals that were alright. I didn't see any other kinds of corals.
Acropora corals, one was bleaching and half dead. This kind of coral is home to the Bandit coral crab, which needs to live in a coral. So if the coral dies, so do the animals that rely on it.
Flowery soft corals that were not bleaching, but also appear to have holes in them. Much of the rocky shore was covered with Button zoanthids which were alright.
Frilly sea anemones and they were all alright. I saw several Haddon's carpet anemone and Giant carpet anemones and one Fire anemone, all of them not bleaching. One of the Giant carpet anemones had an anemonefish.
Fluted giant clam near the arrival spot is still there and not bleaching. We saw it first in Jun 2014.
Spoon seagrass (small and large leaf blades), Sickle seagrass and even some Noodle seagrass.
Tape seagrass had cropped leaf blades, but some patches growing in the rocky areas had longer leaf blades.
I saw one disabled fish trap and there were some floats that look like they mark fish traps in deeper water. I also saw a deep hole (red arrow) with a big pile of coral rubble (blue arrow) next to the hole. A sign of a recent boat strike.

Terumbu Pemang Laut is one of the existing natural shores that may be impacted by the landuse plan by the Ministry of National Development released in Jan 2013 in response to the Populations White Paper with a 6.9 million population target. The dotted margined blue areas are "Possible Future Reclamation".
