The thallus in these algae is coenocytic - i.e it is not divided into separate cells by cross-walls as in most other plants. The whole of the structure seen here is therefore techically a single cell! In spite of this, these algae have a remarkably complex morphology, with the thallus divided into the equivalent of roots, horizontal stems and leaves, although it is assumed that there is no homology between the structures seen in these plants and those of terrestrial groups.

A bit of a digifiddle made a most interesting result.
It used to take a couple of days to make screen or lino print like this, and now 10 minutes will do!

8x10 pinhole very close to water (algae) level, making the algae look much more expansive than it was. That log in the water was only about 25 feet away while the opposite shore was easily several hundred feet away. The foreground is very stretched out.
Efke IR820 with 25a medium red filter and about a 2.5 minute exposure. Developed in Rodinal 1+50 for 10 minutes (drum).
I liked how the seaweed algae moved up and down in a wave as the sea water moved. I tried to make it go faster bur could nit save, so play at x 1.5 speed. this is a video made up of 6 still images
The fur of the Brown-throated Three-toed Sloth (Bradypus variegatus) is impregnated with algae. During the rainy season the fur of the sloth becomes green with growing algae. This sloth was photographed during the dry season when the algae is more brownish than green. It is believed that the algae/sloth is a symbiotic relationship. The hair on the sloth is grooved to provide the algae a place to live. Sloth hair is unique in that if the tip gets wet during a rain the water flows down the shaft (mixed with by-products from the algae) to the base of the hair where it is absorbed through the skin. The leaves that the sloth eats are low in energy producing nutrients (the reason sloths to not move fast). The absorbed by-products from the algae likely provide a needed food supplement. Near Marino Ballena National Park, Costa Rica.
Many species of pink coralline algae, which cements coral reefs together, cover a reef surface in the Southern Line Islands.

Rings of bloom and bust for communities of simple life.
The environment is either sodden with water, drying out or dry and I guess that this reflects upon the growth of this lichen or blue-green algae. There is a brown leaf in a top crack which gives an idea of scale. Static rippling of echoes of water. This image was hiding under a lip of petrified dry waterfall.

This is not a happy picture: It is an algae bloom at the edge of Waiakauhi, the largest natural anchialine pond at Hualalai. A healthy pond should not have this. Still, I could not resist taking a picture of it for its fascinating texture.
It was directly below this photo: Green Leaves, White Flowers
Will have to ask David Chai about those “trails” when I next see him.
