Night Walk at Semakau

It will be very interesting to visit inter-tidal area at this time of the year as the low tide has switched to evening. This is the good time to look at nocturnal marine animals that only come out for feeding at night.
We've been seeing nobel volute laying eggs, and we finally got to see the juvenile voulute.As usual, we saw lots of common sea star (Archaster typicus) at the sand bar area.Another rare find for today is this nocturnal file snake (Acrochordus granulatus). It usually stays in mangrove streams as well as in open water out on the mudflats. Although this snake having banded body that resembles highly venomous sea snake, file snake is not venomous.I took these octopus photos in sequence. Just look at how the colour changes from one spot to another and blend in with the environment. One of the master of the camouflage.

Juvenile eel tail catfish forms a big school for protection in the sea grass lagoon.We saw a total of 3 Knobbly sea star (Protoreaster nodosus) 2 bigger one and another one slightly bigger than 15cm.I saw something moving in a tidal pool under a rock from far. Oh! Is a sea horse.These are some of the flatworm that we saw.When it get darker, guess what! I saw this blue spotted fantailed sting ray that more often seen by divers when diving.The reef collar worm (Family Eunicidae) is also coming out to look for food.Another beauty that we saw is this tube anemone.Due to habitat lost and over collection, cowries are now can be found only at off-shore island.Another master of camouflage is this Spider conch.Just before we board our boat, I saw this toad near the stairs at the jetty.... (not sure if it is waiting to board the boat for a free ride to mainland?)
