Sea anemones of Bickley Bay, Rottnest Island

These are also Heteractis malu, I think.

There are plenty of them!

What are you using to photograph underwater?

I am restricted to taking photos in rock pools when the sun is at just the right angle. Last year I dropped one of my lenses in the salt water. Fortunately it was insured.

I used Olympus Tough 790sw, a point and shoot camera which is waterproof to 3 m. I don't need a housing (which extends it to 40 m) for it as I usually swim near the surface.

Now they have launched Olympus Tough 1030sw, which is waterproof to 10 m, without housing, if I am not mistaken. But I recommend getting a camera with a housing for better protection. And I did.

With my Olympus, I always have to worry about sand or dirt (or even a strand of hair) getting behind the cover of the battery or USB compartment, disturbing the fancy rubber seal. I remember using it in a really turbid water condition before it leaked the last time.

It is also the same camera I used to photograph fishes underwater (see earlier posts).

I witnessed a photographer fall over in a rock pool. The observers were concerned for his welfare. He was concerned only that her had taken his camera into the salt-water with him.

Hopefully, the same thing won't happen to me. I use a non-waterproof point and shoot when I go beachcombing.

Well, that's the good thing about having an amphibious camera like Olympus 790 sw. You generally never have to worry about dropping it into water. Although its image quality certainly won't satisfy a professional photographer. I am alright with it as I can't pay more for a camera. But I think it doesn't show the real colour well.

And I can understand why no one would use an underwater housing to take photos in a rock pool, anyway.

I loved Rottnest! I swam with a 6 foot sting ray in about 4 feet of water for a good 20 minutes.

Hi hotdogman,

Yes! Encounter with those rays is always enjoyable.

I swam with a southern eagle ray for maybe 10-15 min in Bickley bay too. It could easily be 4-5 feet long too. And like you, I didn't have to go very deep, the water must be less than two meters. (Pls search my earlier posts for photo) That was my first experience with a ray.

Later, I saw the same type of ray four times when I snorkeled over the South Cottesloe Reef. Again, two meters or less.

Once, I saw a southern eagle ray with four or five smaller fishes swimming closely beneath it, almost like they were glued to the underside of the ray. That reminded me of a large spaceships with its smaller escorts cruising along in space. If they do decide to swim away from you, they do it gracefully, in their own pace! Not like many other fishes that practically show that they are running for their own dear life : )

Amazing creature!
