Hear all about it!
Eelgrass is also known as Tasman Grass-wrack. This grass is common in the sand patches of sheltered bays of Rottnest.
Most of the animals that live in seagrass meadows do not eat the seagrass itself. Rather, they eat the algae that grow on it, or prey on each other. The exception to this is the Green Turtle and Leatherjacket fish which feed directly on seagrass like the Eelgrass.
Threats include; human impact caused by physical damage from dredging, anchors and motors, pollution and increased nutrient levels in water from incorrect sewage disposal. Natural threats from storm damage and reductions in light from the eutrophication (breakdown of nutrients) process.
