Akashiwo sanguinea is a single-celled organism belonging to a group of algae called dinoflagellates. Akashiwo sanguinea is cosmopolitan (found worldwide) in estuarine and temperate coastal marine waters. Large concentrations of A. sanguinea, called blooms, can discolor water red. Akashiwo sanguinea is harmful to molluscs, and high concentrations called blooms can discolor water red and cause massive fish kills by depleting oxygen in the surrounding water. There have been no reports of illness or other harmful effects from an A. sanguinea bloom in Florida waters.
Rough bubble Algae
Dictyosphaeria cavernosa
(Forsskål) Børgesen, 1932
Description:
The plant forms a large, green, hollow, nearly spherical mass that may be lobed or may collapse or rupture but continues to grow; up to 10 cm in diameter. The wall is crisp, crunchy and show large, angular cells. Differentiated from smooth bubble algae because of the visibility of individual cells (1 mm in size) that make up the algae. They form convoluted, hollow colonies of a continuous layer of green cells.
Habitat:
It grows in most reef environments, attached to rocky substrates and areas of dead coral. On occasion it covers extensive areas, especially under high nutrient levels.
Distribution:
South Florida, Bahamas and Caribbean.

What makes Rose Atoll in National Marine Sanctuary of American Samoa rosy? Coralline algae! Pink coralline algae dominates the atoll's fringing reef, giving the reef a rosy hue.

Test of the 1.3mp video camera from microscopenet.com . Claims 1280x1024 but I see interlacing lines...
The frame rate is only 8fps at this resolution, increases to 15fps at 640x480. This is not what the manual says (15fps and 30fps respectively).
Oh well, at least the image quality is good?
The fish in the image is a Golden Chinese Algae Eater (Gyrinocheilus aymonieri), an ornate color variety of the common Chinese Algae Eater.
This freshwater fish is native to large parts of Southeast Asia, including Northern India and Thailand.
This is photographed from my sweet water tank.
Good morning San Francisco!
I like to share a new perspective view of the San Francisco cityscape in different point of view from Sausalito with these posts. My flavor parts are these green algae posts lit up by the morning sunrise light.
