Autumn leaves caught in the algae at the Mill Pond Dam...

The bubbles were freeze-framed at 1/1250 of a second, frothing the water of the Mullet River as it flows over the 10-foot dam...

Algaes

ISO 100 - 1/200 sec - f/2.8 - 100 mm

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.
