Changi is full of surprises. Like this beautiful blue feather star, with a brittle star living among its many feathery arms!
Here's a closer look at the brittle star (Ophiomaza cacaotica) that lives only in feather stars. It's my first time seeing one in the north!
Eight-armed sea star (Luidia maculata) which had only six arms. Perhaps it's the same one I saw last year here?
Biscuit sea stars (Goniodiscaster scaber) of various kinds. I also saw one small Cake sea star (Anthenea aspera) and one Spiny sea star (Gymnanthea laevis). I didn't come across any Painted sand stars (Astropecten sp.) or any large brittle stars.
Peachia anemone (Peachia sp.) which has a white body column. To be sure that the animal is a new species, scientists like Nicholas need to closely study several animals. The 'brown peachia' is quite rare so we are very lucky to have one more specimen so that we can figure out its identity. Hurray! Changi seems to be where we most commonly find this special anemone.
Haddon's carpet anemones (Stichodactyla haddoni), to smaller Tiger anemones (yet to be identified) and many many Big hermit-hitching anemones just stuck to rocks (also yet to be identified). Among them are cerianthids (Order Ceriantharia) or peacock anemones which are not true anemones and are distinguished by a ring of shorter inner tentacles within a ring of longer outer tentacles. , also . Although they look like sea anemones,
White sea urchins (Salmacis sp.) out and about on the seagrassy shore, many 'carrying' camouflaging seaweed and other debris. I didn't see any Black sea urchins (Temnopleurus sp.) or Thorny sea urchins (Prionocidaris sp.) on this trip.
Pimply Sally-light-foot crab (Plagusia squamosa). I only regularly encountered this crab on our northern rockier shores.
Tidal hermit crabs (Diogenes sp.). A closer look and it turns out to be a little hermit crab that is using a part of a crab limb instead of a shell!
octopus. It looks like the kind I usually only see on rocky shores or reefs.
Miliaris cowries (Cypraea miliaris), a few Onyx cowries (Cypraea onyx) and some Ovum cowerie (Cypraea ovum). There were also many Fan clams (Family Pinnidae) buried in the soft ground.
Sea lettuce (Ulva sp.) that washed up on the shore. Like this Diamond tuskfish (Halichores dussumieri).
Brown wrasse (Halichores bicolor)!
Orange sea cucumber may have a ruptured body. Those yellow things looks like its innards sticking out. But maybe something else is going on.
Thorny sea cucumber (Colochirus quadrangularis) and Pink warty sea cucumbers (Cercodemas anceps), one purple sea cucumber as well as some Smooth sea cucumbers. In the soft silty sand there were many Ball sea cucumbers (Phyllophorus sp.). But we didn't come across the Sea apple sea cucumber (Pseudocolochirus violaceus) that we saw on our last trip here.
Zebra corals (Oulastrea crispata), and I saw growth so Cave corals (Tubastrea sp.) on a shell occupied by a hermit crab! There were a few sea fans but the tide was not really low enough to reveal them properly.
Slender sea pens (Virgularia sp.) and Flowery sea pens (Family Veretillidae). As well as Ball flowering soft corals (Dendronephthya sp.).
Phoronid worms (Phoronis australis). These worms live with cerianthids. Were they living on the much smaller cerianthid in the photo? I must take a closer look at such situations next time!
Fern seagrass (Halophila spinulosa), while Spoon seagrass (Halophila ovalis) were the most abundant as usual.
Aug 2012, following the rediscovery of the shore in Jul 2012. This morning, the haze level was around 180 when we were out there and it was a little uncomfortable.
