patches, the youngest stage of reef development, Barnett
Patches off Hinchinbrook Island. B, Crescentic reef with
hardline growth on the windward side, Eagle Reef, off
Bowen. C, Enclosed lagoonal reefs, infilling from internal
patch reef growth and transport of sediment from the
productive margins, Heron and Wistari Reefs, BunkerCapricorn Group. D, A small senile planar reef with flat top
(still with a living coral veneer) and no lagoon, Wheeler Reef
off Townsville (note the small unvegetated sand cay on the
leeward side). E, The continuous line of outer shelf ribbon
reefs, Yonge Reef near Lizard Island. F, Typical high island
fringing reef, Great Palm Island. (Photos: D. Hopley.)
