In the hot springs on Geyser Hill, these bizarre algae colonies thrive. There are flies that feed on the algae. They have "hot pads" on their feet to protect them from cooking. They kind of skate over the water. The flies are eaten by spiders, who do NOT have the hot pads, so they run, bare foot, (I presume shouting OUCH! OUCH! OUCH!) out onto the mat, grab a fly, and (literally) hot-foot it back to the shore, hopefully before their little toes are burned off. What a life!
The algae already at the door of the little island of Canad Geese.

Porolithon pachydermum (Foslie, 1904) - "reef cement" (calcareous red algae) on a patch reef in the Bahamas.
Rhodophytes are red algae - they are the most common and widespread of marine macroalgae, but they often go unnoticed because of their frequently-dull coloration and nondescript growth forms.
Over 7000 species of red algae are known in the Holocene - most of them are marine, plus some freshwater forms. Rhodophytes are known in the fossil record. The oldest reported fossil red algae are from the upper Mesoproterozoic (~1.2 Ga) of northern Canada.
Red algae vary in coloration - not all are reddish-colored. Rhodophytes can be red, pink, pale pink, lavender, purple, brownish-red, whitish, and yellowish. Fleshy red algae are usually weed-like to mossy to fuzzy in appearance. Calcareous red algae have skeletons with calcium carbonate (CaCO3 - calcite or aragonite). Calcareous red algae are important reef organisms - they include branching forms and crusts. Upon death, the hard part skeletal components of calcareous red algae become biogenic sediments in reef and peri-reef environments.
Porolithon pachydermum is a pinkish to pale-pinkish, calcareous crust that occupies reef crest and near-reef crest facies, where high-energy waves, intense sunlight, and occasional desiccating conditions (from low tides) occur. It has been recognized as a very important reef-building organism. Porolithon crusts frequently have many subcircular openings (see above photo), resulting in a “swiss cheese”-like appearance. These are borings produced by the chiton Choneplax lata (malacos.chez.com/htm/C08G2.HTM) (Mollusca, Polyplacophora).
Classification: Rhodophyta, Florideophyceae, Corallinales, Corallinaceae
Locality: patch reef in western French Bay, southwestern San Salvador Island, eastern Bahamas

algae, we put a glow necklace around him like a belt, he seemed to think it was a cute fashion accesory
A small fountain hidden in the long shadows of the afternoon sun, only the green algae seemed to radiate light, just under the surface of the splashing water.
My fountain badly needed cleaning, but the algae were so photogenic! If you look closely, little eyes are watching you . . . .
This is as macro as it gets folks.
So, last week we got to play with expensive microscopes in Biology class. These had standard lenses and scopes, but they had crazy awesome adjustments, so I was able to focus so well with these microscopes. And on top of it, they were hooked up to computers so we could take pictures for recording what we saw.
Me being a photographer, I stayed after class and played with my microscope and had a little fun.
This is some stringy Algae, or weeds from a pond.
The algae had grown on this rock during the summer and the water flow pushed all the algea to grow in a uniform direction

This is the bottom of the water reservoir of our coffee machine. I've had to wipe green algae off it before. I think that if I moved the machine away from the window it would help. In the meantime I'm emptying it daily and will use Milton to get rid of the algae. I read that it has an important role in the food chain, and may not be harmful, but I don't like the look of it.
Today We're Here are visiting Green Food.
