previous anemone hunts. Dr Daphne has dubbed us her "Anemone Army", and we have mobilised to bring her to see the anemones at Terumbu Semakau!
Terumbu Semakau is a lovely submerged reef that lies just off Pulau Semakau and the Semakau Landfill. On our past trips to Terumbu Semakau, we have seen amazing animals in the reefs, seagrass meadows and sandy shores here. We hope to find some special anemones for Dr Daphne!
As soon as we landed in the feeble first light of dawn, Dr Daphne and the Anemone Army spots a special anemone!
Frilly anemone (Phymanthus sp.) that is often found in sand instead of in coral rubble like the other kinds of Frilly anemones. Today I learnt from her that the six different coloured tentacles closest to the oral disk are NOT the youngest tentacles but instead, the oldest tentacles. The other tentacles arise from these six. Wow!
Reef wriggly star anemones that are commonly encountered on our reefy shores. This anemone has few tentacles and often holds them in pairs, flat against the surface with their tips in wiggles. A few tentacles are held upright like a tent over its mouth on a small oral disk. It's very tricky to take a closer look at these very nervous animals.
Magnificent anemone (Heteractis magnifica) can sometimes clone itself. This is why we sometimes see many individuals clustered near one another, like this bunch we saw today. The anemones in such a cluster often have the same colours.
Giant carpet anemones (Stichodactyla gigantea). Dr Daphne highlights how the tentacles of this anemone are usually constantly in motion, and not due to water movement. We look closer and yes indeed, this is what is happening!
Asparagus soft coral (Family Nephtheidae) for the Fire anemone (Actinodendron sp.)!
Order Zoanthidea. Anemones belong to Order Actiniaria.
Discodoris boholiensis nudibranch, which is quite commonly encountered on our shores.
Fluted giant clam (Tridacna squamosa)! I think it's a 'new' find that was missed when we helped Mei Lin in her earlier survey here. Mei Lin will usually install a marker near those she has recorded, and we couldn't see a marker near this one.
Burrowing giant clam (Tridacna crocea) and it's rather large. Wow!
Noble volutes (Cymbiola nobilis) some of which are very pretty.
Cauliflower coral (Pocillopora sp.). This kind of coral were among those that suffered badly from bleaching last year. More about coral bleaching on Bleach Watch Singapore.
Torch anchor coral (Euphyllia glaberescens). It too was among those that suffered from bleaching. This hard coral is also sometimes mistaken for an anemone.
Snaky sea anemone (Macrodactyla doreensis)!
Sadly, we also came across a very long driftnet that had trapped many colourful fishes, many of which I have not seen before. More about that in this separate post.
Tomorrow, we kidnap Dr Daphne again to visit Cyrene Reef with TeamSeagrass!
