Posidonia australis, also known as fibre-ball weed or ribbon weed, is a species of seagrass that occurs in the southern waters of Australia. It forms large meadows important to environmental conservation. Balls of decomposing detritus from the foliage are found along nearby shore-lines.
Posidonia australis. Posidonia australis seagrass meadows of the Manning-Hawkesbury ecoregion is an endangered ecological community, listed under the EPBC Act of the Commonwealth of Australia on 7 May 2015 [1]
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 ...
Scientists have discovered the world's largest plant off the Australia coast — a seagrass meadow that has grown by repeatedly cloning itself. Genetic analysis has revealed that the underwater ...
Researchers were stunned when they discovered a species of seagrass had effectively cloned itself for 4,500 years and covered nearly 80 square miles. Scientists Find World’s Largest Plant In ...
Shark Bay has the largest known area of seagrass, with seagrass meadows covering over 4,000 square kilometres (1,500 sq mi) of the bay. [1] It includes the 1,030-square-kilometre (400 sq mi) Wooramel Seagrass Bank , the largest seagrass bank in the world [ 1 ] and contains a 200-square-kilometre (77 sq mi) Posidonia australis meadow formed by a ...

Wrack is part of the common names of several species of seaweed in the family Fucaceae.
Few species were originally considered to feed directly on seagrass leaves (partly because of their low nutritional content), but scientific reviews and improved working methods have shown that seagrass herbivory is an important link in the food chain, feeding hundreds of species, including green turtles, dugongs, manatees, fish, geese, swans ...
