Pulau Sekudu is an small island located just south of Chek Jawa, Pulau Ubin. It is a restricted area and permit from the National Parks Board (NParks) is required to gain access to this island.
The Google map above show you the location of Pulau Sekudu (south of Pulau Ubin, north of Changi Village).
My first trip to this island was in August 2013 to conduct a similar survey of the marine life on this island. You can read more about the animals I saw during that trip here.
As the tide recedes, Pulau Sekudu "grows" in size as the intertidal zone is being exposed. However, the tide was not the lowest today, so the island was not fully exposed.
On a not very good start, my first animal encounter was a dead fish. Could this be a dying fish that floated over from a nearby fish farm?
There were many stone crabs (Myomenippe hardwickii) out on the shore. Some of them was seen alone while some were in small number hiding in a large rubble.

Realised that the tail looked like it has a pair of eyes staring at you.

Other than the plain sand star, I also came across a few crown sea stars (Aquilonastra coronata) of varying size. Usually, they are spotted under stones or on coral rubble. However, the ones that I saw were wondering on the sea lettuce seaweeds. the rest of the team came across a pretty orange variation of the crown sea star. Sometimes, we call them rock sea stars.

This trip was made possible with permit and permission from the National Parks Board (NParks) and Chay Hoon for the boat arrangements. We will be making another trip here in two days' time.
