Species

Lyngbya is a genus of cyanobacteria, unicellular autotrophs that form the basis of the oceanic food chain.

As a result of recent genetic analyses, several new genera were erected from this genus: e.g., Moorea, [2] Limnoraphis, [3] Okeania, [4] Microseira, [5] and Dapis. [6]

Lyngbya species form long, unbranching filaments inside a rigid mucilaginous sheath. Sheaths may form tangles or mats, intermixed with other phytoplankton species. They reproduce asexually. Their filaments break apart and each cell forms a new filament. [7] The mats grow around atolls, salt marshes, or fresh water. [8]

Some Lyngbya species cause the human skin irritation called seaweed dermatitis. [9]

Some Lyngbya species can also temporarily monopolize aquatic ecosystems when they form dense, floating mats in the water.

Ingestion of Lyngbya is potentially lethal. [8] Most commonly, poisoning is caused by eating fish which have fed on Lyngbya or which have fed on other fish which have consumed Lyngbya. [8] This is called " ciguatera-like" poisoning. [8]
