The stomach of the harbor porpoise Phocoena phocoena (L.)
The morphological and cytological characteristics of the stomach of the harbor porpoise (Phocoena phocoena (L.)) are described from dissections and histological preparations. The stomach consists of the following three compartments: forestomach, with keratinized stratified squamous epithelium and we...

The morphological and cytological characteristics of the stomach of the harbor porpoise (Phocoena phocoena (L.)) are described from dissections and histological preparations.

The opening from the fore-stomach to the main stomach is located near the esophageal opening. A sphincter is not present, but the opening is surrounded by several epithelial folds.
