Last Week's Reef Survey @ Big Sister Island.....

BWV ReefFriends conducted another reef survey last week. This time at Big Sister island.

Was assigned to do the deep Line Intercept Transect (LIT) survey and shallow fish survey. Currents were manageable and vis was about 1.5m to 2m.

So here are what I came across along the transect lines;

Most corals look like that they were recovering from the bleaching. However, there are some that did not make it.

The Bubble Tip Anemones are still bleaching. Hope that they will recover soon!

Fishes like Tomato Anemonefish and Filefish.

Lots of Crinoids/Featherstars out and about! From big big ones to small small ones.

Many Orange Brittle Stars on a Sea Fan!

A Basket Star!

Can you see the tiny Top Shell Snail in the pic? It was about 1cm big!

A few of these Sap-sucking Sea Slug (Thuridilla gracilis) were seen.

Lastly, the Nudibranch! From the top is the Pimply phyllid nudibranch (Phyllidiella pustulosa). The middle one is a tiny tiny Dermatobranchus nudibranch (Dermatobranchus sp.) and the one at the bottom is a Reliable Chromodoris nudibranch (Chromodoris fidelis)
