Remarks. The species is widespread in the SML samples. It is one of two species found alive. B. obtusata is currently reported at 300 m WD in the Gulf of Naples (Bonaduce and Pugliese, 1979), between 600 and 2669 m WD in the Atlantic-Mediterranean Region (Bonaduce et al., 1983), at 145- 165 m water depth along the Norwegian and British coasts (Sars, 1928) and in the Recent Mediterranean Sea between 150 and 2905 m (Puri et al., 1964). Also the fossil record of this species points to bathyal palaeoenvironments (Tyrrhenian Sea: Colalongo et al., 1988, 1990; Le Castella: Colalongo, 1965; Capo Milazzo: Sciuto, 2003, 2005; Furnari: Sciuto and Rosso, 2008; Vrica: Colalongo and Pasini, 1980).
