Algae has so many Leaves! I know it does, but this was the first time I noticed in detail.
* I've also uploaded the same from a Mobile phone camera - Sony Xperia Arc S. For image quality comparison. It's down here in the comment Box or in the link below...
The picture here is shot in DSLR - 18MP and the one in Mobile phone is shot in 6MP.

Freshwater diatoms, an algae, surrounded by some lime scale on aquarium glass.
Most diatoms are unicellular, although they can exist as colonies in the shape of filaments or ribbons (e.g. Fragillaria), fans (e.g. Meridion), zigzags (e.g. Tabellaria), or stellate colonies (e.g. Asterionella). Diatoms are producers within the food chain. A characteristic feature of diatom cells is that they are encased within a unique cell wall made of silica (hydrated silicon dioxide) called a frustule. These frustules show a wide diversity in form, but usually consist of two asymmetrical sides with a split between them, hence the group name. Fossil evidence suggests that they originated during, or before, the early Jurassic Period. Diatom communities are a popular tool for monitoring environmental conditions, past and present, and are commonly used in studies of water quality.
Not normally rehired as attractive but essential and here in a good light with suggestive highlights. Formatted for mobile phone wallpaper

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.
