Although OCEANA could not document these gardens made up only by Callogorgia verticillata in the
maritime area of OSPAR, it is quite likely that they occur in Portuguese waters. Nevertheless and focusing
only in the OSPAR area, mixed garden of Callogorgia verticillata and other gorgonian and sponge species
have been recorded in the Gorringe Bank.
DEPTH: 135 - 350 m
TYPE OF SUBSTRATE: These gorgonian gardens grow on rocky substrate with a great variety of bottom
types: non-sediment bedrock, bedrock covered by a lot of sediments, rocky slabs and stones on sandy
bottom.
4.4.1 Mixed garden of Callogorgia verticillata, Viminella flagellum, Tedania sp. and other
demosponges
DESCRIPTION: These mixed fields develop on the shallowest area of the bathymetric range of
Callogorgia verticillata along with another species of predominant gorgonians such as Viminella flagellum
and sponges such as Tedania sp. and other desmosponges not identified. Sea urchins (Centrostephanus
longispinus) are also abundant, as well as shoals of Anthias anthias.
DEPTH: 135 - 150 m
TYPE OF SUBSTRATE: The species that make up this garden develop on rocky substrate, on a sandyrocky
mixed bottom.
