The reason why we've called it this? Because it waggles its white butt! Pei Yan took this great video clip of the shrimp 'dancing'. Check out her blog for more stories and sightings.
sea fans (Order Gorgonacea) growing on hard surfaces on the shore. I came across several different kinds of ovulids on these sea fans! Some animals live only on sea fans, like the Ovulid snail that's at the base of the sea fan in this photo.
Ovulid snails (Family Ovulidae) that I've not seen for a long time! Some of them I've only seen at Beting Bronok.
Tiger anemone has yet to be identified.
Thorny sea cucumbers (Colochirus quadrangularis) and Warty pink sea cucumbers (Cercodemas anceps) and Ball sea cucumbers (Phyllophorus sp.).
Sea apple sea cucumber (Pseudocolochirus violaceus). In the past, we used to see several of these animals.
Cerianthids (Order Ceriantharia) aka Peacock anemones on this shore than other parts of Changi. They are not true sea anemones! Among the many cerianthids is this intriguing dark one. We still haven't sorted out the identities of our cerianthids yet.
Ball flowery soft coral (Family Nephtheidae). One of them had a white snapping shrimp that only lives in these soft corals. I also saw many Slender sea pens (Virgularia sp.), a few flowery sea pens (Family Veritillidae) and Spiky sea pens (Pteroides sp.).
Elbow crabs (Family Parthenopidae) that look like they are mating. I often see various small crabs mating or about to mate near cerianthids. I have no idea why.
Miliaris cowries (Cypraea miliaris) are often found in pairs. I also saw several Calf moon snails (Natica vitellus) and some Fan clams (Family Pinnidae). We didn't see many nudibranchs today.
Black sea urchins (Temnopleurus sp.) were huddled together in a small part of the shore.
White sea urchin (Salmacis sp.), and another smaller one with brighter pink square-tipped spines. The shells around the smaller sea urchin were probably dropped by the sea urchin which was carrying them.
Cake sea stars (Anthenea aspera), many Biscuit stars (Goniodiscaster scaber) of various sizes and a few sand stars (Astropecten sp.). Pei Yan saw a Luidia sea star (Luidia sp.). But we didn't see any other special sea stars. There were also many flat-armed brittle stars as well as other brittle stars.
Hairy spoon seagrass (Halophila decipiens) (orange arrow). These were growing among ordinary oval leafed Spoon seagrass (Halophila ovalis).
Nest mussels (Musculista senhousia). I saw this on this shore in Jul 2012 as well as at another Changi shore.
Fern seagrass (Halophila spinulosa), all looking fresh and green.
dugong feeding trails in the seagrass meadows? We saw more furrows on this Changi shore in May 2011. We also saw dugong feeding trails in the seagrass meadows across the narrow Changi Creek near the buildings with the red roofs in Jan 2013.
eige sheet ascidian growing on seagrasses.
Zebra corals (Oulastrea crispata) and various colourful sponges.
Nest mussels (Musculista senhousia) blanket large parts of the shore. We saw three people collecting on the shore.
Estuarine seahorse (Hippocampus kuda), and I didn't see many fishes. I didn't see one but Chay Hoon saw a Seagrass octopus. Although still lively, the Changi shores we have visited recently seem to be changing.
The rest of the week, we head out Southerwards to check out some other reefier shores.
