taxon notes

In zebrafish, No stomach, small intestine, or large intestine can be distinguished. However, differences can be found in the morphology of the mucosa columnar epithelial cells and the number of goblet cells, suggesting functional differentiation. The intestine has numerous folds that become progressively shorter in a rostral-to-caudal direction. Proportionally, these folds are significantly larger than the finger-like intestinal villi of mammals and other amniotes (Wallace et al. 2005). Columnar-shaped absorptive enterocytes are the most numerous in the zebrafish intestinal epithelium. Goblet cells are the second most populous epithelial cell type.
