Other plants that colonised the sea, such as salt marsh plants, mangroves, and marine algae, have more diverse evolutionary lineages. In spite of their low species diversity, seagrasses have succeeded in colonising the continental shelves of all continents except Antarctica.
One of the largest aquatic plants in the world is the Bolivian waterlily, which holds the Guinness World Record of having the largest undivided leaf at 3.2 m (10 ft 6 in) diameter; the smallest is the rootless duckweed, which is only 1 mm (0.039 in) across.
Posidonia is a genus of flowering plants. It contains nine species of marine plants [ 3 ] (" seagrass "), found in the seas of the Mediterranean and around the south coast of Australia . The APG system (1998) and APG II system (2003) accept this genus as constituting the sole genus in the family Posidoniaceae , which it places in the order ...
More than 90% or about 1,500,000 ha (3,700,000 acres) of the world's natural sea buckthorn habitat is found in China, Mongolia, Russia, and most parts of Northern Europe. [4] Sea buckthorn USDA hardiness zones are about 3 through 7. [4] In some areas it is considered invasive, due to its ability to outcompete smaller native species. [6]
The so-called "stinging seaweed" Microcoleus lyngbyaceus is a filamentous cyanobacteria which contains toxins including lyngbyatoxin-a and debromoaplysiatoxin. Direct skin contact can cause seaweed dermatitis characterized by painful, burning lesions that last for days.
Marine life, sea life or ocean life is the collective ecological communities that encompass all aquatic animals, plants, algae, fungi, protists, single-celled microorganisms and associated viruses living in the saline water of marine habitats, either the sea water of marginal seas and oceans, or the brackish water of coastal wetlands, lagoons ...
The characteristics of the Posidonia plant, its growth dynamics and the large amount of biomass produced, are factors that can sustain very diverse plant and animal communities. Distinguished are: epiphytic communities (that is, bacteria, algae and bryozoa that colonise the surface of the leaves and rhizomes of the plant), vagile and sessile ...
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.
