Watersipora subtorquata (d'Orbigny, 1852)
IUCN
NCBI
EOL Text
The species can form either extensive encrusting sheets (20 cm in diameter or more) with broad spreading lobes, often overgrowing older layers; or erect slightly foliaceous colonies with lobes composed of autozooids arranged back-to-back. The colour of the colony is highly variable. On occasion, colonies form a broad and extensive orange-red region around the edge of the colony, becoming paler and greyish towards the centre. Alternatively, colonies may be dark sepia, black or deep purple with a narrow orange margin.
Autozooids are sub-rectangular or slightly hexagonal, sometimes narrower proximally (closest to the colony origin). They are relatively large (approx. 1mm in length)
