intestine AAO:0000246 ANISEED:1235303 BSA:0000093 BTO:0000648 CALOHA:TS-0490 EFO:0000834 EMAPA:32874 EV:0100071 FMA:7199 GAID:295 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.
