Other shores surveyed (May 2026)

Besides the main surveys, the team split up on some dates to also guide. To take advantage of the very  few super low tides during daylight! Many team members visited various parts of Changi. Other shores visited on this tide include Pasir Ris and Sentosa Tg. Rimau.

People don't believe me when I say, Changi is among the best shores to see a wide variety of nudibranchs. No need to dive! Here's photos of recent sightings by the team, mostly by our nudi whisperer Jianlin who visited in April. Love the photo of the big orgy of Jorunna nudis complete with laid egg ribbons and chomped up sponges. Also, a new Singapore record of Limenandra fusiformis, many colourful slugs and flatworms too.

It's a relief to know there are still manysea stars on this shore which is so well visited and facing heavy boat traffic. Knobbly sea stars large and medium sized were seen, as well as a variety of other sea stars.

Other exciting observations include a super tiny frogfish, octopus and her eggs laid inside an empty Noble volute shell. The mama octopus constantly guards her eggs literally with her life, often dying of starvation in the end. Another special sighting was of 6-8 Blood spotted swimming crabs (Portunus sanguinolentus) which so far, the team has only seen once on the intertidal at Kusu Island. There were also other special crabs and a spearer mantis shrimp. As well as interesting fishes including a cusk-eel, which we usually only commonly see in the South.

Volunteers from Singapore Youth Voices for Biodiversity brought SPS Goh Hanyan to Pulau Hantu (5 May) and Cyrene (21 May). Where she saw for herself how mangroves can thrive alongside man-made coastal protection structures such as seawalls, highlighting how nature-based solutions can complement engineered measures. And how coastal protection measures can be thoughtfully designed to integrate existing recreational uses like intertidal walks, fishing and diving, ensuring these spaces remain accessible and enjoyable for the public.

On 20 May, Zen Xuan He and I supported a walk with about 40 PSC scholars at Kusu Island. So they could see for themselves how corals are thriving less than half an hour away from the Central Business District. Full of interesting marine life like Knobbly sea star, Upside down jellyfish and crabs - thanks to Zen for finding and sharing about them.

Followed by a visit to the Marine Park Public Gallery at the St John's Island National Marine Lab. Where we learned about the exciting 100k corals project from Dr Lionel Ng. Quite amazing to see the work on cultivating coral fragments to plant out onto our shores.

We sure managed to cover a lot of ground this last cycle of low spring tides!
