I visited Changi Beach today and there were many things to see on this period of low spring tide.
There were many patched of seagrass but the animals there were more attractive to take pictures of. So some types of seagrass can be seen in some of the following images.
On the shore, there were plenty of white sea urchins (Salmacis sp.) and small hermit crabs running around. As usual, the sea urchin had various types of camouflage.

Also plentiful on the shore are the thorny sea cucumber (Colochirus quadrangularis). I think I also saw a few pink warty sea cucumber (Cercodemas anceps). In fact, I have one picture of the feeding tentacles of the pink warty sea cucumber. The two sea cucumber looked rather similar and it is easy to overlook them if not carefully observed. I do remember seeing a few sea cucumbers with yellowish background. Next time I must look carefully.

The Pink warty sea cucumber is less common and has pink warty bumps instead of soft thorns.There were also many smooth sea cucumbers seen half buried in sand.

Two octopus were seen, with one hiding in an empty shell and another was stranded on the sandy shore. Sankar transferred the stranded octopus into the shallow pool and it inked shortly after.

Also seen were many long bristleworms moving in and out of their tube holes and a fan worm.
Mei Lin was wondering what other animals she can find as the waves were coming in and she saw a juvenile dog-faced water snake (Cerberus rynchops).

Changi beach is filled with many critters. Some of the animals there are enlarged versions of what I have seen. Amazing.
After two days of shore trips, I am feeling the aches from all the bending. It is sure great workout sessions.
Tomorrow, I will be visiting a special place off mainland - Beting Bronok.
