Spartina is a genus of plants in the grass family, frequently found in coastal salt marshes. [3] Species in this genus are commonly known as cordgrass or cord-grass, [4] and are native to the coasts of the Atlantic Ocean in western and southern Europe, north-western and southern Africa, the Americas and the islands of the southern Atlantic Ocean; one or two species also occur on the western ...
Seagrasses then evolved from terrestrial plants which migrated back into the ocean. [ 14 ] [ 15 ] Between about 70 million and 100 million years ago, three independent seagrass lineages ( Hydrocharitaceae , Cymodoceaceae complex, and Zosteraceae ) evolved from a single lineage of the monocotyledonous flowering plants.
Zostera marina is a flowering vascular plant species as one of many kinds of seagrass, with this species known primarily by the English name of eelgrass with seawrack much less used, and refers to the plant after breaking loose from the submerged wetland soil, and drifting free with ocean current and waves to a coast seashore.
The purple sea fan is found in the western Atlantic and Caribbean, with a range extending from Bermuda and Florida and the Gulf of Mexico to Curaçao.It grows near the shore in shallow water in areas with strong wave action and on deeper outer reefs with strong currents down to a depth of about 15 m (49 ft).
Marine botany is the study of flowering vascular plant species and marine algae that live in shallow seawater of the open ocean and the littoral zone, along shorelines of the intertidal zone, coastal wetlands, and low-salinity brackish water of estuaries. It is a branch of marine biology and botany.
A planted reef aquarium filled with Bladed sand moss (Caulerpa prolifera) A seagrass aquarium housing several seagrass meadow inhabitants.

The plant's preferred salinity range is 25 to 38.5 parts per thousand with a temperature range of 20 to 30 °C (68 to 86 °F). It is found from the low-tide mark down to depths of 30 metres (98 ft), depending on water clarity. It often grows in meadows with other seagrasses where it is the climax species. [7]
