On 23 Jul 2016, we visited Semakau East to check out the coral bleaching situation.
Bleaching happens when corals (and also other cnidarians) lose the symbiotic algae in their bodies which help produce nutrients. It is the algae that give the animals their colour. Scientists think that most bleaching is caused by an increase in sea surface temperature. Find out more about bleaching in the Bleach Watch Singapore blog.
Moon coral (Diploastrea heliopora).
Feather star (Order Comatulida).
Black phyllid nudibranch (Phyllidiella nigra).
Curryfish sea cucumber (Stichopus vastus). Think it's my first or second time seeing it! We hardly see them on our reefs. The animal may disintegrate if it is handled or take out of water for a long time. So please don't touch it.
Fluted giant clams (Tridacna squamosa) are not bleaching.
