Under the Stars at Pasir Ris Park 150109

A couple of days later, I was back out in the 'wild' with a couple of friends - this time at Pasir Ris Park...at night! It was really chilly when we got there and the strong wind blowing continuously didn't help. The cold did keep away the mozzies though. Okay, I concede that I'd rather be cold than to 'donate' blood! Apologies in advance for the not-so-good quality of the pics. Shaky hands... Credit goes to Zelin for helping to ID the pics..thanks!

Found this tiny sea urchin taking refuge among the sea lettuce.

Could it be a Heart Urchin (Order Spatangoida) by any chance?

This is probably a Sentinel Crab (Macrophthalmus sp.), half-buried in the sand.

There were quite a few of this Striped Bead Anemone along the beach.

Yellow egg capsules of a drill (Family Muricidae) attached to a rock, possibly that of a Bumpy Drill. The egg capsules of drills are first yellow, but turn purple when the eggs hatch.

A half-emerged hermit crab.

A small goby [perhaps a Plain Goby (Family Gobiidae)?] found in a shallow pool of sea water along the beach.

Walking on, we encountered another Striped Bead Anemone having a snail for dinner...

..and it wasted no time in tucking in!
