Info
Posidonia australis has large bright green stems, fast-growing leaves of approx. 30 - 60 cm in length and these are 6 -14 mm wide and rounded at the end.
This seagrass, one of 8 endemic seagrass species of the Posidoniaceace family in Australia, lives at shallow depths in estuaries, coastal lakes and sheltered coastal waters.
Posidonia australis, like all other seagrasses, plays an important role in the sea, not only being extremely productive, but also providing a nursery, hunting ground and food source for a variety of animals.
Small animals such as fish, pipefish, seahorses and a whole range of other species use seagrasses as an effective hiding place against predators and spend their first time in the protection of these grasses.
For manatees, dugongs and turtles, seagrass provides them with food.
The predators of the seas, in turn, know that seagrass meadows are an area of rich prey.
In addition to the functions mentioned above, seagrass also produces oxygen (O) and consumes carbon dioxide (CO2).
These reasons suggest that seagrass meadows, like mangrove forests, require priority protection by humans.
One thing should be clear: if the sea dies, so does the earth!
