Flower of the sea
|[Note Guidelines] Photographer's Note|
|Sea Anemone, common name for marine, flowerlike polyp having a cylindrical, or vaselike, body. Many species are colored; large specimens may attain a diameter of 1 m (3 ft). The body is closed and attached to rocks or coral at one end and, at the other end, has a central mouth surrounded by tentacles armed with nematocysts (stinging cells and thread cells that paralyze and entangle the small fish and marine animals that constitute its prey). The slitlike mouth opens into a short esophagus opening into the body cavity. At each end of the mouth, a permanent pore opens into a ciliated groove, called a siphonoglyph, in the side of the gullet, through which a continuous current of water flows, carrying oxygen to the tissues and removing waste matter. The body cavity is divided into a number of sacs by septa extending from the body wall. These septa increase the surface available for the secretion of digestive juices and the absorption of nourishment, and they contain the gonads that produce the sperm and eggs.|
Most sea anemones reproduce sexually; budding and fission are comparatively rare. The eggs are usually fertilized in the gastric cavity, and the young are discharged from the mouth as free-swimming larvae, which soon attach themselves to surfaces. Hermit crabs sometimes attach sea anemones to their shells (see Symbiosis). Some anemones become completely parasitic on certain species of jellyfish.
Scientific classification: Sea anemones make up the order Actiniaria of the class Anthozoa.
I took this photo at the Georgia Aquarium. This anemone was in shallow water so I didn't get much distortion. Have a great weekend!

I love the light on the tentacles, Alli. Wonderfully sharp details of this sea anemone, and gorgeous colors. A great POV.
I hear wonderful things about the new Georgia Aquarium. I hope I can visit it some day.

What a lovely shot. The colors are so nice and the focus is sharp. Well exposed. How are you doing? TFS!
Great sharpness, Alli, lovely colors and a really very interesting object! Its petals look so smooth and transparent, I almost feel like touching them.
A stunning display!
The details are amazing and the colours luminous.
It is a great pleasure to view your work, and I have added the photo to my new theme "under and above the seas"
Thanks for sharing
