Here we go again! Another 2am wake up call this morning and off we were to Chek Jawa for an intertidal survey which we encountered many 'S's! What are these 'S's?
Hollow-cheeked stonefish (Synanceia horrida)! When stepped on, the stonefish is capable of injecting toxin that would cause extreme pain. Unfortunately, these guys are too well camouflaged and hard to spot and avoid.
Blue-spotted fantail ray (Taeniura lymma). The stingray has serrated spines that can cut deeply and introduce venom into the wound that can cause excruciating pain. Interestingly, there was also a Fan-bellied filefish (Monacanthus chinensis) swimming across in this photo. Do we consider this as a photo-bomb? Hehe!
Seagrass filefish (Acreichthys tomentosus) that were either resting or swimming around in the tidal pools.
Biscuit stars (Goniodiscaster scaber)! They are everywhere and found in various positions and sizes.
Knobbly sea stars (Protoreaster nodosus) on this trip as usually we would only find a a couple or a few on our previous surveys. Today I saw about 8-9.
Cake sea star (Anthenea aspera) which is as colourful and speckled with patterns as decorated cakes that we eat.
Spiny sea star (Gymnanthenea laevis).
Eight-armed sand star (Luidia maculata).
Aeolid nudibranch (Cratena sp.) found on hydroids.
Red egg crab (Atergatis integerrimus) in the northern shores as they are more usually sighted in the southern shores as they are mainly found on reefy areas. This crab was found at a crevice of the Pore hard coral (Porites sp.).
Other than the Pore hard corals, we also came across this version which I'm not too sure if it is the Pore hard coral or the Sandpaper coral (Psammocora sp.).
Anemone coral (Goniopora sp.) that we commonly see in the south.
Ball flowery soft corals are not as abundant here as compared to our remote northern shore at Beting Bronok.
Sea fans or Gorgonians (Order Gorgonacea) doing? They are still around but definitely not as abundant as those that we find at East Coast or Changi shore.
Barrel sponges (Xestospongia testudinaria).
Mangrove horseshoe crab (Carcinoscopius rotundicauda). As part of the ritual, the males which are smaller hitch a ride on the females using their specially adapted hooked first legs.
Graceful cowrie (Purpuradusta gracilis).
Haddon's carpet anemones (Stichodactyla haddoni) are doing very well at the southern parts of Chek Jawa! Glad that they are not bleaching.
Thank you Nparks for giving us permission to document the shores of Chek Jawa as the intertidal area and the waters around it is out of bounds to the public.
