Beting Bronok Exploratory Trip

I was told to look out for stingray if I am going to Beting Bronok (BB) as my CH was stung by sting-ray just last month also during an exploratory trip.

True enough, we saw this Mangrove Whip Ray (Himantura walga) half burried in the sands and it remains there even when I move just next to it to take photo. When the water is clear, no problem of spotting it and just do a detour. If the water is milky, the risks of stepping onto one will be very high. Sting-ray have a very sharp spine at their tail and can easily puncture our shoe when we accidentally step on them.
I also saw this very pretty Blue spotted fantail ray (Taeniura lymma). Blue spotted ray are quite a shy fish and will swim away once we get near them.Is the breeding seasons for this Hairy sea hare (Bursatella leachi). There are just every where.
This is another quite common but rarely seen Polybranchia orientalis slug as their colouration and shape of algae, made it difficult to spot. Their cerata will just drop when disturbed.
A very unique Blue dragon (Pteraeolidia ianthina) nudibranch that are labeled as solar power ready! The juveniles feed on zooxanthellae-rich hydroids to recruit them. The zooxanthellae will multiply in the nudibranch tissues. The zooxanthellae will photosynthesized and past the nutrient to the nudibranch!We also saw this Discodoris boholensis nudi.There are lots of sea star at BB such as this Biscuit Star (Giniodiscaster scaber).
Not just biscuit, there are lots of Cake Sea Star (Anthenea aspera) too. We sae the one on top and also some with pink colour.
The Sea Pen take the opportunity in fast moving water to filter-feed.
I am not sure why the colour of this Ghost shrimp is not the usual orange /red.
During spring low tide, the tide will go down very fast and very low. These file fish was caught unprepared and trapped in this very tiny tidal pool.
This Moray eel face the same situation and got stranded on the dry area.
This little Butterfly fish is happily swimming among the seaweed.I spotted 11 Sea horses this morning and is one of my highest count in any one trip.
There are lots of Onxy cowry (Cypraea onyx) too.
Less than 1 cm, this Allied cowrie need a very sharp eyes if you thinking of finding them.
This Noble volute is quite big in size compare with volute that I saw at Changi.
The highlight of the day is this very beautiful and rare Bailer shell.
