Finally, I get a good look at a seahorse on Changi! I almost missed it as it was so well camouflaged.
The rest of the team also saw some seahorses including a tiny one. It's good to know that the Estuarine seahorse (Hippocampus kuda) is still on Changi. Other interesting fishes seen were many slender Seagrass pipefishes, and a pretty colourful Diamond wrasse (Halichoeres dussumieri).
Sea apple sea cucumber (Pseudocolochirus violaceus) today. I saw four in a small area on the shore. On my last trip here in April, I did see two Sea apple sea cucumbers but no seahorses.
Biscuit stars (Goniodiscaster scaber) from tiny ones to medium sized ones. Plenty of Thorny sea cucumbers (Colochirus quadrangularis) and Warty pink sea cucumbers (Cercodemas anceps). In the soft silty sand there were many buried Ball sea cucumbers (Phyllophorus sp.) and many Cerianthids (Order Ceriantharia) with Phoronid worms. And squirming around were many flat-armed brittle stars.
plain and beige animal. It has black feeding tentacles.
Seagrass octopuses on this shore. I've seen fishermen collect these harmless beasts to use as bait. I'm glad this practice has not wiped them out.
Common whelk (Nassarius livescens) has a very long foot that it uses to 'hop' around quickly when it needs to. The little round patch on the foot is the 'door' or operculum that is used to seal the shell opening when the snail retracts into its shell. There were many Calf moon snails (Natica vitellus) out and about. And the rest of the team saw several Miliaris cowries (Cypraea miliaris).The only slug I saw today was a single Geographic sea hares (Syphonota geographica).
Polka dot anemone. It has yet to be identified. So far, we've only seen these at Changi and Cyrene Reef.
Haddon's carpet anemones (Stichodactyla haddoni) in the process of eating a large crab! The Tiger anemones were still common here too.
Nest mussels (Musculista senhousia). I took a closer look to see what animals are found on this mat. These include Slender sea pens (Virgularia sp.), cerianthids, Fan clam (Family Pinnidae), sand stars (Astropecten sp.) and even a mangrove seedling that had taken root in the mat.
Silt flatworm that looks like mobile phlegm. Being very flat, it can squirm among the mussels and squeeze through the tiniest gap in the shells to eat them!
Hairy spoon seagrass (Halophila decipiens)? I saw these yesterday too at another stretch of Changi, and we have seeing these at Changi and at Punggol. Hope we can sort this out eventually.The meadows are dominated by Spoon seagrass (Halophila ovalis), but there were also some Fern seagrass (Halophila spinulosa). The seagrasses looked good today.
sea fans (Order Gorgonacea) and I saw one Ball flowery soft coral (Family Nephtheidae). As well as many sponges growing on hard surfaces.
Spiky sea pens (Scytalium sp.) on the shore and I took a closer look at one that was still submerged to see how the polyps in the colony were arranged. Oh, they emerge perpendicular to the 'leaves' thus forming a net of tiny tentacles to trap food.
Black sea urchins (Temnopleurus sp.), gathered together in numbers. I notice some of them look slightly different.
Raffles Museum of Biodiversity Research who are working on another stretch of Changi. They have found lots of interesting things too including another Numbfish (Narcine sp.)!
chitons (Class Polyplacophora) here! These animals are molluscs with a flexible armour.
Tomorrow, another early start, this time to check up on Labrador for TeamSeagrass monitoring.
