We explore a part of Changi that we haven't visited for many years, and are stunned by some amazing sightings!
Sea apple sea cucumber (Pseudocolochirus violaceus). Its bright colours warn of its toxic nature so don't touch it or bring it home!
The most astonishing sighting for me was a Common sea star (Archaster typicus), my first time seeing one on Changi! Sadly, this sea star is no longer as common as it used to be, although it is still the most widely distributed of our sea stars.
Eight-armed sea star (Luidia maculata), but it only had six arms.
Biscuit sea stars (Goniodiscaster scaber) large and small. I saw one small Cake sea star (Anthenea aspera) and several flat-armed brittle stars.
Black sea urchins (Temnopleurus sp.). I also saw many large White sea urchin (Salmacis sp.) and one tiny Thorny sea urchins (Prionocidaris sp.).
Thorny sea cucumber (Colochirus quadrangularis) and many Pink warty sea cucumbers (Cercodemas anceps). There were also lots of Thumbs up sea squirts (Polycarpa sp.).
Ball sea cucumbers (Phyllophorus sp.), usually buried with only their feeding tentacles sticking out. Also many Orange sea cucumbers buried in the soft silty sand and Purple sea cucumbers.
Haddon's carpet anemones (Stichodactyla haddoni) here, and a Kite butterflyfish (Parachaetodon ocellatus) was swimming very close to one. I've seen this intriguing behaviour several times elsewhere too.
Five-spot anemone shrimp (Periclimenes brevicarpalis), while many had tiny anemone shrimps. I also came across several Tiny carpet anemones (Stichodactyla tapetum).
Tiger anemones, one Peachia anemone (Peachia sp.), one Plain anemone (Paracondylactis sinensis). Also some Swimming anemones (Boloceroides mcmurrichi). There were only a few Cerianthids (Order Ceriantharia) also called Peacock anemones although they are not true sea anemones.
Slender sea pens (Virgularia sp.), more than I usually see at Changi. Finally, I got a closer look at the delicate polyps that make up this colonial animal.
Flowery sea pens (Family Veretillidae) and a few Sea pencils.
Common sea pen (Pteroides sp.) and it was teeming with tiny Painted porcelain crabs (Porcellanella picta) and one Colourful tiny brittle star (Ophiothela danae).
Candelabra sea fan.
Sally-light-foot crab (Grapsus albolineatus) but somewhat different from the ones I usually see. It ran away before I could take a closer look at it.
Swimming crabs (Family Portunidae) of all kinds. I saw one with banded legs (Charybdis annulata) that disappeared rapidly among the seaweeds. There were also many Striped hermit crabs (Clibanarius infraspinatus).
Miliaris cowries (Cypraea miliaris), usually seen in a pair. I haven't seen these in large numbers at Changi for a long time. I also saw one Onyx cowries (Cypraea onyx) . As usual, there were lots of Ovum cowerie (Cypraea ovum) too.
Fan clams (Family Pinnidae) on the shore and I noticed they had different coloured bodies. There were also some scallops (Family Pectinidae) and lots of other clams were seen on another portion of the shore that I didn't get to explore.
Pink moon snails (Natica zonalis) and I saw one Tiger moon snails (Natica tigrina).
octopuses. Some parts of the shore were covered in a soft layer of nest mussels (Musculista senhousia).
pipefishes! Chay Hoon finally spotted our first seahorse sighting in a long long while at Changi.
Zebra corals (Oulastrea crispata). Also various sponges of all shapes and colours.
Spoon seagrass (Halophila ovalis) with large leaves, and nice growths of Fern seagrass (Halophila spinulosa). There was a bloom of Sea lettuce (Ulva sp.) blanketing the shore, so I'm not sure how extensive this seagrass growth is.
MORE shore trips at ungodly hours in the week ahead. Can't wait to see what we will find!
