Sargasso Weed,Sargassum natans gathers in large mats in the middle of the Atlantic Ocean. Storms breaks up these mats and they then drift via currents all over the Atlantic. Little gas floats allow this brown algae (Phaeophyta) to ride atop the waves in the open ocean.You REALLY need to see this one at full-resolution: www.flickr.com/photos/nashworld/7068343447/sizes/o/in/pho... ...to appreciate the hydroids covering almost the entire surface of this algae.
A seeweed known as Huiro Palo massively harvested in Chile for export as a thickening agent in foods and cosmetics. The ecological consequences can be devastating.
Bodanella (bow-dan-ell-a) lauterbornii, a branching filamentous brown alga. Nearly all brown algae are marine organisms, but this species is found in the bottoms of freshwater lakes. Bright field. data on this strain.
