Walters Shoals
The Walters Shoals is a group of submerged mountains off the coast of Madagascar. Despite being south of Cape Sainte Marie - Madagascar and east of Richards Bay at the African coast, the tips of some of the mountains are only below the surface. The Walters Shoals is home to many species of fish, crustaceans, and mollusks.
It was discovered in 1963 by the South African Hydrographic Frigate SAS Natal captained by Cmdr Walters. When found it had a huge population of Galápagos sharks but they have since been fished out.
