These openings surrounded by glandular tissue, especially exit opening. Modified dorsal caudal-fin scales appear as rather poorly focused " ghost " images in upper half of picture, above main body of pump chamber.

(B) Illustrates relationship of modified dorsal caudal-fin lobe squamation to glandular groove. Note that modified scales together with their epidermis form a movable flap just lateral to surface of rays and glandular groove. Free border of this flap occurs along ventral margin of ventral row of scales and at posterior edge of posterior scale of ventral scale row.
