The following photographs are of a preserved hectocotylized arm I of S. hoylei, 100 mm ML, Hawaiian waters.
Figure. The distal portion of the hectocotylus of S. hoylei. The suckers on the right side of the photograph are much smaller that those to the left, nearer the tip. Also heavy pigmentation occurs along the crest of the keel.Photograph by R. Young.
Figure. Left - Photomicrograph of the large suckers near the tip of one hectocotylized arm of S. hoylei. The oral surface of the suckers are covered by a thick, fleshy tissue. The horny sucker ring is the dark amber band. Right - Side view of a sucker from the base of the same arm. The sucker has a very large, fleshy oral hood. Photographs by R. Young.
Figure. Oral view of one hectocotylized arm of S. hoylei in the region of multiple series of suckers. This photograph was taken of the opposite arm from that in the description on the previous page.Photograph by R. Young.
Figure. Oral view of one hectocotylized arm of S. hoylei proximal to the multiple-sucker-series region. Note the broad separation of the sucker series and the postion of each sucker at the end of an elongate base.Photograph by R. Young.
Figure. Side view of the midregion of one hectocotylized arm of S. hoylei. The palasade effect of the long sucker bases can be seen through the skin. Photograph by R. Young.
