Summary
| Description |
Udotea flabellum (Ellis & Solander, 1786) - mermaid's fan alga on shallow, aragonitic sandy seafloor. Udotea is a calcareous green alga - the fan-shaped blade has tiny particles of aragonite (CaCO3 - calcium carbonate). After the alga dies and the soft parts decay away, the aragonitic portions become clay- & silt-sized seafloor sediments. A significant percentage of shallow seafloor and shoreline sediments in the Bahamas is from calcareous algae. Many carbonate petrologists suggest that ancient fine-grained limestones (micritic limestones; micrites) are diagenetically altered deposits of calcareous green algae. Classification: Chlorophyta, Caulerpales, Halimedaceae Locality: shallow seafloor just west of North Point Peninsula, southeastern Graham's Harbour, northeastern San Salvador Island, eastern Bahamas |
