Highlights: Sea fan & sponges Sponge with brittlestar - Gorgonocephalus sp. Antipatharian coral Antipatharian coral & sea fans Sea fan Octopus - Graneledone ? Soft coral with brittlestar - Gorgonocephalus sp. Purple soft coral Paromola cuvieri Anglerfish - Lophius piscatorius Healthy Lophelia reef Anglerfish - Lophius piscatorius
Sponge aggregations and gorgonians are common with a number of large white sponges and patches of coral. Coral rubble is evident on the entire transect. Approaching a mound summit the ground comprises of thick coral reef, with increasing presence of Lophelia pertusa and Madrepora oculata compared to the base of the mound where Solenosmilia is very common. There are many fish present including monkfish, blue-mouth rose fish, Lepidion eques as well as large crabs, Chaceon affinis and spider crabs. Overall the site is noted for all three species of stony reef.
