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.

Cyanobacteria (blue-green algae)

Cyanobacteria (blue-green algae) are a type of microscopic, algae-like bacteria which inhabit freshwater, coastal and marine waters.

Cyanobacteria photosynthesise like plants and have similar requirements for sunlight, nutrients and carbon dioxide to grow and produce oxygen. There are many different varieties of cyanobacteria. While often a green or blue-green colour, they can also be white, brown, blue, yellow-brown, or red.

If conditions are suitable, cyanobacteria can increase to excessive levels and form visible ‘blooms’ which can lead to poor water quality and the potential for toxicity.

Cyanobacteria can cause environmental problems, disrupt drinking water supplies, recreational activities and water-dependent industries, and pose a risk to livestock, wildlife and human health.

How about this for Smile on Saturday's combination of flora and fauna... A snapping turtle laying eggs and covered in algae.

The fish in the image is a Golden Chinese Algae Eater (Gyrinocheilus aymonieri), an ornate color variety of the common Chinese Algae Eater.

This freshwater fish is native to large parts of Southeast Asia, including Northern India and Thailand.

This is photographed from my sweet water tank.

I'm no expert so can only wonder whether it's a good place or not for a mother Mallard with new brood.

Blue-Green Algae (Cyanobacteria) - they can release toxins that are harmful to humans, pets, livestock.

An arrowhead crab, Huenia heraldica, decorated itself with algae to make itself look like a piece of Halimeda algae.

Tell me this algae doesn't look like a nebula, birthing stars from galactic matter. So neat.

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.

Thank you everyone for visiting, commenting and fav'ing - very much appreciated!

I discovered this green algae covered slough (secondary channel of a river delta) in Moss Landing, California. Although a bit disgusting, I think the swirls and reflections make up for an interesting scene.

This is the lake in the Japanese Garden area in the Missouri Botanical Garden. Thank you for having a look.

Looks pretty menacing. I think the thing that looks like a bit of piece of lokum/Turkish delight is a sea gooseberry.

Fantastic geology in Northern Ireland.

Green algae decorates the spring at Pinkerton Hotsprings along US 550. It's not hot.

algae in late afternoon on the beach.

Where the sun shines directly on the New River it has become a sea of green and red algae. Whilst the ducks seem to be managing ok it doesn't seem the most comfortable environment for them to have to live in
