Yellowstone in winter is a true wonderland. Unbelievable. Wish I knew what I was doing then and got more good shots but this one is a keeper. :)

Green algae in the still water of a pond in The Fox Island Allen County Park near Fort Wayne, Indiana
Today I took a short hike to this place where I thought I would see some mud cracks due to the drought. To my surprise, I found a pool of colorful water. I suspect the colors were caused by the algae as some of the water puddles in the salt ponds were quite colorful. The sight of this colorful pool was actually quite eerie especially there was nobody around in this area which is quite far out into the bay. As I did not have my ultrawide angle, I had to take multiple shots and stitch them into a pano.

Thallus to 12 cm in diameter, saclike, hollow, spherical when young, becoming convoluted, ruptured, and irregularly lobed when old. Firm, tough texture, consisting of large bubble-shaped cells that are easily seen by eye. Rhizoids are short, branched or unbranched.
Daughter segments are formed as occasional segments become inflated, forming large monostromatic bladders attached to the parent plant. They may remained attached to the thallus or break away and become independent plants. Grass green, but sometimes blueish in color. Dictyosphaeria cavernosa is found attached to rocks or coral rubble on shallow, calm reef flats and in tidepools. Young plants may form small clusters of "bubbles" scattered among turfs on hard substrate. Older plants can form large convoluted mats from 1 to 10 cm thick that may cover large areas subtidally to 59 meters. Nuweiba, Gulf of Aqaba, Egypt.

an adult emperor angelfish feeding on algae on the sea bottom outside the lagoon
( angel fish are often very colourful - and this is one of the largest angelfish I have seen)
like many angelfish the young of this species has a very different colour pattern - one can be seen here:

heavy crop cos I don't dive as deep as this!!
In shallow pools left behind as the falls flow receded. If you look closely at the edges of each bubble, you can see reflections of the other bubbles around them...and I think I'm in there, too.
