Susan's Reef, Kimbe Bay: A Symphony of Red Gorgonians

Susan's Reef offers a unique visual experience distinct from other sites in Walindi, largely due to its remarkable concentrations of red whip gorgonians (Ellisella sp.). These dense, swaying formations create a sense of underwater wilderness, accentuated by vibrant tangles of crinoids that cling to the gorgonians and other reef structures. This distinctive growth is most prevalent at the southern end of the reef, between 22 and 15 metres, where it rises from a saddle that connects Susan's Reef to the larger Vanessa Reef.

As you follow the reef northward, you'll encounter a dramatic eastern wall, dropping steeply into the depths, contrasting with a gently sloping hard coral garden on the western side. Near the top of the connecting saddle, around 25 metres, some paler gorgonians can be observed. When the current is active and favourable, small sea pens push through the sand to feed, adding another layer of delicate life to this transitional zone.

Ascending past the primary concentrations of whip gorgonians, three prominent red gorgonian formations become visible, acting as natural landmarks on the reef. The deepest of these, at 14 metres, is a reliable spot to locate the longnose hawkfish, often found perched amongst its branches. This fascinating predator, with its distinctive elongated snout, camouflages itself against the gorgonian's intricate structure, waiting for prey.

Above 10 metres, the reef structure shifts dramatically, becoming almost exclusively dominated by dense fields of staghorn corals. This shallower section forms a vibrant, bustling ecosystem, providing shelter and hunting grounds for myriad reef inhabitants. Amidst these hard coral thickets, several sea anemones host three different species of anemonefish, their bright colours a stark contrast against the coral backdrop. This upper reef stratum provides an ideal habitat for these symbiotic relationships.
