Here's a glimpse at some of the sea cucumbers of Singapore's seagrass meadows.
Often mistaken for worms, sea cucumbers are related to sea stars. Sea cucumbers can be round as balls, long and worm-like, or even U-shaped. Seagrass meadows on our northern shores like Changi beach are great for spotting a wide variety of sea cucumbers. As well as other marine life.
Sea Apple sea cucumber is highly toxic to eat and advertises it with eye-poking colours.
Pink warty sea cucumber and Thorny sea cucumber are particularly common on Changi and some other northern shores. Their bright colours also suggest that it's probably not a good idea to eat them.
Purple sea cucumber. Most sea cucumbers have tube feet which are used to cling to things.
Ball sea cucumber which can be plentiful on our sandy shores. At high tide, the feathery feeding tentacles emerge to gather titbits from the water. At low tide, these are retracted and there is hardly a trace of the sea cucumber on the surface.
Plasticky sea cucumber is another burrowing sea cucumber that is sometimes seen among our seagrass meadows of the north.
Polka-dotted sea cucumber seems to be seasonally common on our northern seagrass meadows.
Where can I see sea cucumbers in Singapore?
- Join intertidal walks by NParks at Chek Jawa, Pulau Ubin.
- Check out these opportunities to explore our shores through walks, or during volunteer work for our shores.
