The day began ominously with red swathes of rain sweeping over the entire Singapore! This is a great example of a Sumatras squall, an angry wall of wind and water sweeping over the Malay peninsula! More about these awesome storms in my earlier blog post.
Smooth ribbon seagrasses (Cymodocea rotundata). It is listed as Critically Endangered in Singapore and so far, I've only seen it at Chek Jawa and Cyrene Reef.
massive oil spill in 2010, lots of crude oil ended up on the shore and over the years got buried beneath the sand. There was also another smaller oil spill that washed up here in July, last month.
Long-spined black sea urchin (Diadema sp.)! My first time seeing it here at Tanah Merah! This sea urchin has spines that can poke painfully, so it's important not to handle them. Even dead ones.
Large-toothed flounder (Family Paralichthyidae). The fish begins life like most other fishes with eyes on both sides of the head. As it develops, one eye rapidly moves so both eyes end up on one side of the body and the fish lies flat on the ground! Here's diagrams of this.
squid (Family Loliginidae). We often see live squids here but at night. During the day, most animals hide, except for dead animals of course.
cuttlefish bones which are entirely different.
Nerite snails (Family Neritidae). These marble-shaped snails may look alike but there are often different species living on the same shore. He explains how those that live lower down on a rock can cling on more firmly. This is because he has done a study on them in school. The study suggests this is probably because these snails have to put up with stronger waves, than snails that live higher up on the rocks.
sand collars made by moon snails. They do look like elaborate sand art!
Soldier crab (Dotilla sp.)!
Common sea stars (Archaster typicus)! They survived the oil spill! We gently look at their underside to see their spines, tubefeet and mouth and watch as they turn themselves over. We should not do this more than once as it takes a lot of energy for the sea star to do this.
Horn-eyed ghost crab (Ocypode cerathophthalmus) buried in the sand! It looks a little surprised when I gently unearthed it.
Striped hermit crab (Clibanarius infraspinatus) that had just moulted! The team also gathered other moults. We also had a look at Moon crabs (Asthoret lunaris).
Brown sweetlips (Plectorhinchus gibbosus) which is sometimes seen on our reefy shores. We return the fish and other creatures after we have a look at them.
Amazing marine life has settled on the artificial shores of Tanah Merah, including lots of hard corals and otters were also spotted here in June, just two months ago.
|A reef of various hard corals is growing at the Ferry Terminal,|
but it can only be seen at super low tide.
