I'm certainly not a marine biologist, but am informed that this is a 'Dactylometra Quinquecirrha' type jellyfish, so I'll take their word for it. Their tentacles are covered with stinging cells that attach themselves to anything that touches them and injects a venom into it's prey. Fortunately I didn't get the opportunity to experience this in action even though I'm told it's not fatal. My biggest problem capturing this image is that there is absolutely nothing stable to attach a camera to underwater. Tripods are useless, I'm moving, the camera is moving, the sea creatures are moving, all at different rhythms (guess I didn't need to bring the cable release). All in all, this was probably the most serene and beautiful creature I've ever witnessed; it's pulsating motions and delicate nature were extremely enjoyable.

I'm climbing down inside a volcano crater and am amazed with the variety of rock/soil colours that are so neatly piled about.

passing for an assortment of freshly mined diamonds, these rough 'gems' are actually grains of refined sugar. they are spilled upon a deep-blue CD case which gave us a nice colour backdrop and texture. the crystalline grains of sugar average around 1/60 of an inch.

the meter-deep water is covered with a perfect layer of duck weed appearing as a green carpet spreading through this banyan forest.

the surf is definitely 'up' today

Many northern states like Montana have an abundance of colourful stones delivered by glaciers long ago. These happen to be at the edge of a lake under a few inches of water. The entire beach area and bottom of the lake (as far as I could see) was covered in this manner and the stones just under the water provided great rich colour with minimal wave distortion. To be able to shoot straight down and not have any perspective in the stone pattern, I stood in the water and waited for the ripples to disappear before capturing this neat texture image.
