Species

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

Lyngbya species form long, unbranching filaments inside a rigid mucilagenous 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.[2] The mats grow around atolls, salt marshes, or fresh water.[3]

Some Lyngbya species cause the human skin irritation called seaweed dermatitis.[4]

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

Ingestion of Lyngbya is potentially lethal.[3] Most commonly poisoning is caused by eating fish which have fed on Lyngbya or on other fish which have done so.[3] This is called ciguatura poisonining.[3]
