pyloric caeca
Fish gut extensions
Pyloric caeca are finger-like pouches extending from the digestive tract of many fish, located where the stomach meets the intestine.
They increase surface area for nutrient absorption and enzyme secretion.
The number varies widely by species—salmon may have dozens, while some fish have none.
Also called pyloric ceca.
Singular: pyloric caecum.
