It's the Sargassum seaweed (Sargassum sp.) season where most reefs are ringed by thick blankets of the seaweed. However, this did not stop us from visiting our southern reefs!
Spotted-tail frogfish (Lophiocharon trisignatus)!
Frogfishes are interesting because they have a bait-like structure that lures smaller fishes or prey into the area their the mouth and before you know it, the frogfish has gotten its meal.
Physogyra Coral (Physogyra sp.)! It's only my second time seeing this on our intertidal shores.
large bubbles that obscure the skeleton. These are possibly modified tentacles that inflate during the day. The sacs contain symbiotic algae (zooxanthallae) and the expanded surface area probably helps increase photosynthesis activity.
Cave corals (Tubastrea sp.)! The tentacles are all retracted when the corals are out of water.
Circular mushroom corals.
Moon coral (Diploastrea heliopora). The corallites are regularly spaced out and give an overall regular tidy pattern.
Fluted giant clam (Tridacna squamosa)!
Bulb-tentacled anemone (Entacmea quadricolor).
Magnificent anemones (Heteractis magnifica).
Five-spot anemone shrimp (Periclimenes brevicarpalis) among the tentacles of the anemone.
Tiger cowrie (Cypraea tigris)! My second time seeing this handsome and huge cowrie.
According to the Singapore Red Data book, although this cowrie was considered one of the commonest cowries of the Indo-Pacific, and present on Singapore reefs in the past, the tiger cowrie is now exceedingly rare.
Razorfish (Family Centriscidae) which usually swim together and they indeed look at razor blades!
Orange-white black flatworm which we rarely see on the shore seems to be in season recently as it appeared in most of our southern shore trips.
Alicia sea anemone (Alicia sp.)!
