Mediterranean Sea, shallow waters and caves.

Remarks.

Arachnanthus oligopodus was initially described as a species of the genus Cerianthus by Cerfontaine (1891a), and was moved to the genus Arachnanthus by Carlgren (1912b). This is a very common species in several areas of the Mediterranean Sea, especially on the Italian Coast (Carlgren 1924; Torelli 1961). This species has a number of descriptions with appropriate levels of detail (e.g., Cerfontaine 1909; Carlgren 1912a). However, knowledge of the species is still incipient. Biological aspects, especially on the life cycle, are still quite unknown.
