Patterns in the green algae in the Binnenalster lake at Hamburg. The early morning sun casting a shadow on the discarded liquor bottle.
Rather out of focus, but not too much the worse for it, in a sort of Trippy way...

What is this? Kind of algae or fruits of algae? Found at the shore of the Baltic Sea in Northern Germany.
Long strands of river algae, found in Mekong, are sprinkled with sesame seeds, tomato and garlic and left to dry int the sun, Laos.

Seen here is a model-based reconstruction of life on an ancient seafloor during the Silurian. This is a public exhibit at the Cleveland Museum of Natural History in Cleveland, Ohio.

Many times a day an army of men worked hard on the sun to clean up the beach where loads of algae were left on the sand.
algae (ăl`jē) [plural of Lat. alga=seaweed], a large and diverse group of primarily aquatic plantlike organisms. These organisms were previously classified as a primitive subkingdom of the plant kingdom, the thallophytes (plants that lack true roots, stems, leaves, and flowers). More recently, most algae have been classified in the kingdom Protista or in another major group called the eukarya (or eukaryotes), which includes animals and higher plants. The algae have chlorophyll and can manufacture their own food through the process of photosynthesis. They are distributed worldwide in the sea, in freshwater, and in moist situations on land. Nearly all seaweeds are marine algae. Algae that thrive in polluted water, some of which are toxic, can overmultiply, resulting in an algal bloom and seriously unbalancing their ecosystem.

Fossil red algae from the Mississippian of Kentucky, USA.
The squiggly carbonized compressions in this rock have been interpreted as fossil rhodophytes - red algae. Rhodophytes are the most common of all marine macroalgae, but they often go unnoticed due to the dull coloration and nondescript growth forms of many species. Over 7,000 species are currently known. Despite the common name "red algae", colors include red, pink, whitish, lavender, purple, yellow, and brownish-red. Many rhodophytes are calcareous - they have hard parts of CaCO3, usually as branching forms or crusts. As such, they are important reef organisms, and contribute large amounts of biogenous CaCO3 grains to seafloor sediments. Fleshy red algae are mostly weed-like or mossy or fuzzy.
Classification: Plantae, Rhodophyta
Stratigraphy: Salem Limestone, Middle Mississippian
