Trichodesmium thiebautii (light micrograph) Trichodesmium thiebautii is a cyanobacterium, or blue-green alga, that forms colonies of cells. In high concentrations, they create golden-brown surface mats, often referred to ?sea sawdust,? in the Gulf of Mexico. These large concentrations, called blooms, are sometimes associated with fish kills and can cause dermatitis or ?swimmer?s itch? when handled or contacted. When blooms die and decay, they can discolor the water pink to red. Toxin production by this species is being investigated. https://www.flickr.com/photos/myfwc/8678780050
