Description

The photos here are both from the West Ridge and the Cove, and at the bottom of this page is a compilation of video shot at the two sites.

Underwater the ridge becomes a large, diagonal saw-tooth ridge covered in soft coral and sponge and teeming with blennies, hawkfish and anthias. Moving towards the cove the slope gives way to large lettuce coral sheets and finally a sand and broken coral base terrain punctuated by coral stacks, like every increasingly sized mushrooms. Every surface that isn’t hard coral is encrusted with soft coral and sponges.

There are lots of mid-sized reef fish attracted by the growth.

Some fish, like these Golden Rabbitfish, always travel in pair, and never take more than a quick bite before moving on.

We saw at least one, if not several Bearded Scorpionfish on every dive in the Andaman Sea. Only this one was yawning.
