Monorhaphididae is a monotypic family of siliceous deep sea Hexactinellid sponges. The single taxon is the type species Monorhaphis chuni, a sponge known for creating a single giant basal spicule (GBS) to anchor the sponge in the sediments. The species was described by Franz Eilhard Schulze in 1904 from specimens collected by the German Deep Sea Expedition in 1898-1899.^[2]
