Many posts have been done on various blogs on last Sunday's trip to Semakay landfill (please refer to bottom of this post for the links) so I think I'll focus more on those that others did not emphasize on their posts.
On Sunday afternoon, we all set off to Semakau and this was my first OJT with the Semakau guides. OJT stands On-the-Job training which is designed to allow volunteers to get their training in a flexible manner that suits the volunteer's schedule, as well as the schedule of the volunteer trainers. This was an opportunity for me to observe and learn how to conduct a fun and effective tour where I also will learn the route and the procedures for the walk.
This time, Juanhui is my "mentor" as I tagged along with her to guide "Mangroves" group. We had a group of friends from LTA. Yay.
At first, the sky really gloomy as mainland Singapore was raining and it seems that the rain is moving towards the south. When we disembark from the boat, the rain arrived too, and it was heavy. Thank God it moved as quickly away as it came.
We have with us Dr. Yaacob Ibrahim, Minister for Environment and Water Resources, and also his family. What a honour to have him join us to explore Semakau.
Dr. Yaacob and family and also a non-family member: Ron Yeo. More about Dr. Yaacob's interesting interaction and encounter that day on the Nature Scouter blog.
Soon we arrived! When we disembark from the boat, the rain arrived too, and it was heavy. Thank God it moved as quickly away as it came.
During the landfill tour, filled with weird jokes, my attention was diverted to something more interesting... Raffles Lighthouse (Pulau Satumu). This marks the southermost of Singapore's straits and it holds one of the best reefs intertidally and subtidally. Do note that this is not Pedra Branca as some may get confused with.
Beside Raffles Lighthouse is Pulau Biola, aka Violin island.
The best part of the whole Semakau trip arrived which is the intertidal tour. Before that, we have to taste some bitter before sweet. That will be to walk through a mosquito infested trail that was quite flooded due to the rain. Everyone was carefully threading to avoid stepping into the dirty puddles. The funniest thing is that when we came back at the end of the walk, everyone simply care less and walk on the puddles quickly. This is because they already got soaked enough during the intertidal trip, and also we all want to run away from the mosquitoes.
After some sharing on mangroves, creeper shells etc, its time to cross the glorious seagrass meadow of Semakau which Team Seagrass proudly monitors its health. It is important to cross through a line called the zone of death so that we do not destroy the other parts of the meadow by careless trampling.
I found this beautiful Pebble crab (Family Leucosiidae) along the way. These crabs tend to hide in small pools or along stream banks. They are slow-moving and tend to hide during the day. As such, they are rarely seen. Glad we saw it!
Like most leucosiids, they feed on small animals in the substrate,
The participants were quite excited to see so many common seastars which they can learn more about them and get to feel and touch them first hand. It is important not to leave them out of water too long.
Baby noble volutes and moon snail.
Juanhui sharing the wonders of our marine creatures with the participants :-)
This is actually my first time seeing Chromodoris lineolata nudibranch. How exciting even for a guide. Haha.
More about this charismatic nudibranch at the where discovery begins blog.
We also encountered many sea cucumbers. Don't miss the cute photo of Dr Yaacob and his family with the three different sea cucumbers at the Nature Scouter blog.
According to A guide to seashore life in Singapore,
"The local conch shells are characterised by a narrow, blade-like operculurn on their foot. The black-lipped conch (shell 3-5cm) is common in muddier substrates adjacent to reefs, being a detritivore and herbivore. They move in jerks, using their bladelike opercula to thrust them forward. In neighbouring countries, they are a popular seafood. A related species, S. canarium, which is white to yellowish in colour, with a thicker shell, is rare nowadays, but the dead shell can still be seen along the shores."
Great that we can still find them at Semakau.
In all, it was a great OJT trip where Juanhui and I shared with the participants of Semakau intertidal area. I enjoyed myself! Looking forward to the next guiding, which will be some time, after my exams in May.
