Shark Bay Posidonia australis Clone (At Least 180 km)

Genetic sampling across Shark Bay identified one widespread polyploid Posidonia australis clone spanning at least 180 km. The clone occurs in fragmented near-shore meadows; the 200 km² figure is a historical meadow-area estimate, not a solid rectangle.

Measurement basis

The horizontal scale is the sampled clone span. Gaps between genetically identical meadow fragments are preserved conceptually.
