 The ocular retractors branch from the pedal muscles; they bifurcate towards their anterior ends, and supply the inferior tentacle retractors.The length of the radula is about an inch, and 0.4 inch in width at the anterior end, tapering to a point posteriorly, with about 104 transverse rows of denticles (tiny teeth).The rows of denticles are forming an obtuse angle of about 130°, salient posteriorly.
