When the mantle cavity is opened the two gills can be readily seen. In the photo above, the opening to the mantle cavity is to the left. Water is sucked into the rear of the mantle cavity (to the right), then blown back out across the featherlike gills which can be seen above and below. The visceral mass is visible between the gills. This individual washed up on a beach at Seaside, Oregon, so there is some sand in the gills. Photo by Dave Cowles, July 2009

The tentacle clubs have suckers with no teeth. Notice the toothed ring from another (arm) sucker on the upper left. Also notice that the proximal part of the tentacle (to the right) is not covered by suckers. Photo by Kirt Onthank, 2009

The suckers are on pedicels (stalks). Photo by Kirt Onthank 2009

Some of the suckers contain a ring of teeth. The scale in the background is millimeters. Photo by Kirt Onthank, 2009

The arms are angular in cross section. Photo by Kirt Onthank, 2009

The beak appears similar to a parrot's beak. The roots of each beak, however, extend well back into the buccal mass (the white mass of muscle around the beaks here), becoming wider, softer, and thinner as they go. The smaller beak (on the right above) is dorsal. Between the beaks is the radula and the salivary papilla. The esophagus passes back through the heavy, muscular buccal mass to the stomach.
