On the shore directly opposite NSRCC, there is a huge sand bar full of life.
Button snails lie buried just beneath the sand. These are hunted by predatory Ball moon snails and Weasel olive snails. Here's a video of Button snails, the predators that eat them, and what happens after they die. There are also lots of Cake sand dollars.

At the base of the seawall, exposed only at the lowest spring tides, there is a narrow strip of coral reef!
Giant carpet anemones. I even saw several Clown anemonefishes in one of them!
stonefish, which are commonly encountered on all our East Coast shores. Especially near seawalls and reefy areas. These fishes are almost impossible to spot. If you step on the fish, its tough spines will penetrate even through thick soled booties. These act like hypodermic needles, injecting a venom that can be fatal to humans. The stonefish neurotoxin is considered the most deadly of the fish venoms. The victim should be brought to hospital as soon as possible. So do take note and work out an evacuation route from your destination to the nearest pick up by an ambulance.
Guided intertidal walks at East Coast Park
Ideally, it's best to visit a shore with an experienced and trained guide. Why?
See more! Experienced guides are familiar with the terrain and seasons of the shores. They can show you more during the short window of low tide. They can also tell you more about what you see so you can learn more.
Be safe: The shores are not dangerous if you know what you are doing, but for those unfamiliar there are potential hazards. With a professional guide, even young children can interact safely with the shores.
Minimise your impact: Every inch of the shores are alive with small animals and growing plants. An experienced guide will help you see more and yet minimise the impact of your visit.
Have a great time! Guides are eager to ensure you have an enjoyable visit. Whether you are just there to see what's so special about the shores, or if you need more details for a project or have a special area of interest. Do tell your guide, who will gladly try to help you.
Consider joining walks by Young Nautilus who have pre-planned visits and will also gladly organise trips to fit your schedule. More about their public programmes.
If you do want to visit on your own, here's some issues you should take into consideration ...
When is the best time to visit our shores?
Singapore waters tend to be murky and cloudy (like 'kopi susu') because of the high sedimentation. Thus, if you go at high tide, you can't see much. However, just because you can't see something, doesn't mean there is nothing there.
The rich shorelife is more easily seen at low tide. The lower the tide, the larger the expanse of shore exposed and a wider variety of shorelife can be seen.
It's best to visit with the outgoing tide. The water is clearer as the tide falls, and in areas where a calm shallow lagoon forms at low tide, behind a sand bar. The water tends to get murky as the tide turns and water rises and rushes in.
Singapore has two low tides and two high tides a day. The height of the tide is not the same every day. High and low tides do not happen at the same time every day, and the highest and lowest tide level change every day. Tides suitable for a visit to the shore do not necessarily occur on a weekend. Suitable tides usually fall before sunrise and after sunset. There are few suitable tides during daylight hours.
Here's more about the tides: what causes them, and about Singapore's tides.
How low should the tide be to see something at East Coast Park?
The ideal tide for intertidal exploration is 0.1m or lower for Changi tide tables. Such low spring tides tend to occur near or after sunset at this time of the year. So be prepared with a small torch.
Where to find tide information?
The marinas based at Changi provide on their website, the hour-by-hour predicted tides for Changi. Links to these and more about Singapore's tides here.
Safety on the shore!
Comply with all prevailing COVID regulations. Visit the NParks SafeDistance website to check on the current crowding at the location, and for the latest COVID regulations.
Lighting and rain: Immediately evacuate to one of the park shelters at the first signs of the weather turning bad. Lightning can occur without rain. Get the latest weather situation here: radar readings updated every 10 mins.
Don't touch! All animals defend themselves from predators or they will be eaten up and soon become extinct. Some of these animal defences can cause humans irritation, pain or even worse injuries and death. As with any nature walk, it is important to respect the wildlife: do not touch animals, don't poke them, leave them alone. Cover all skin that can be exposed to the water; wear covered shoes. Do not walk on bare feet. Closely supervise young children who may accidentally touch animals, then rub their eyes or put fingers into the mouth.
If we are not careful, we can damage the shore when we visit. Be gentle. Watch your step. Avoid wading into deeper murky waters as you won't be able to see what you are stepping on. Don't poke animals or dig them up or bring them home. Take only photos.
Sharing your photos is one way to give back for the damage you cause to the shore. No matter how careful you are, you will cause some damage.
