Abstract
The attachment of Clinostomumsp. to the oesophagus of the bird definitive host Ardea cocoiis reported. The parasite attaches to the mucous layer of the oesophagus by the acetabulum, oral sucker, and oral collar. The mucous layer of the oesophagus engulfed by the oral sucker presents an intense liquefactive necrosis, and the engulfment is not likely to contribute significantly to the attachment of the parasite. The oral collar of the parasite, surrounding the oral sucker, is juxtaposed to the oesophagus mucous layer, showing a perfect fitting of both surfaces. It is concluded that the main attachment mechanism of the parasites to the oesophagus of the host is provided by the acetabulum and by the juxtaposition of the oral collar of the parasites to the oesophagus host surface.
