Pulsing Xenia to be exact. When the water is still, you can see the flower heads pulse and contract as they filter the water in search of nutrients. Very cool to watch, but they are considered a pest in reef tanks. That's all the animals for now, the next sets will be of the landscapes and snow.
The fog was so thick that I missed this when I first walked around the bend. It loomed up at me out of the fog and stopped me dead in my tracks. The picture simply cannot convey the sheer size of this radiotelescope. It simple boggles the mind.
Behind me, and to the right were a row of trees which blocked the sun until it was high in the sky (wel, high for 10am) then at which point it blew away the fog. Here you can see the effect.
Not the main scope, but one off in the distance. I was very lucky, there was heavy fog surrounding the whole area, lending atmosphere and a sense of isolation to my work.
