The Ibiza Channel has a depth of 2,000 metres and contains escarpments and seamounts that are favourable for the presence of vulnerable species. The Stone Sponge Seamont is a remarkable seamount that extends from a depth of 1,300 metres to a summit of 730 metres. It is named after the community of siliceous sponges of the species Leiodermatium pfeifferae that inhabit it. The area is notable as a distribution area and connectivity corridor for species of community interest, including the Loggerhead Turtle (Caretta caretta) and the Bottlenose Dolphin (Tursiops truncatus). Additionally, there have been sightings of the Sea Lamprey (Petromyzon marinus).
