Hello readers,
The main highlight for the Pulau Semakau trip was definitely not the rubbish. It was a several-hour intertidal walk (the picture depicts the shores of Pulau Semakau). We got to explore the mudflats and observe the flora and fauna there. En route, my brother and I spotted around two eagles soaring high above us. They were presumably white-bellied sea eagles (which can be found in Singapore).
Not long after, the group of about 20 of us reached the mudflats. Because the tide was extremely low that day, we were able to see the fauna living in the tidepools. Despite the tide being low, however, the water was still almost up to my knee level (about 20cm deep) at the deeper parts. I suggest that if you want to go for the intertidal walk in Pulau Semakau, it is best that you wear boots or shoes with long socks (which is what I wore). Never wear slippers or sandals or even worse, go barefoot. For all you know, you could step on a stonefish or sponge and get hurt. If you want to explore the mudflats of Pulau Semakau and find the trip meaningful, you must appreciate nature and not be afraid of dirt (frankly, I was a little wary of the water level rising above my shoes but I got used to it later).
At a first glance, the murky waters seem lifeless and dull, but at a closer look, the organisms that secretly live in the mud would be noticable. Farther away from the sea, there would be little holes in the sand with several minute balls of sand near it. Those holes are made by sand bubbler crabs, which sift through the sand for microscopic food and produce the little balls of cleaned sand as a result, which they then chuck away. Numerous mangrove trees can be found farther away from the sea (the picture depicts a close-up photo of a mangrove tree). The guide pointed out to us the seedlings of the mangrove tree. To increase the chance of the seedlings' survival in such a harsh environment, the seedlings germinate while they are still on the tree and are later carried off by the high tide. By the way, the below video shows what the mudflats of Pulau Semakau would look like at a glance.
Okay, that is enough for the day.
