In zebrafish, the posterior intestine has short longitudinally arranged epithelial folds which are similar to the colon of higher vertebrates[ZFIN] UMLS:C0009368 SCTID:302508007 Although all vertebrates have a digestive tract and accessory glands, various parts of this system are not necessarily homologous, analogous, or even present in all species. Therefore, broad comparisons can be best made under the listings of headgut, foregut, midgut, pancreas and biliary system, hindgut.[uncertain][VHOG] EMAPA:18939 AAO:0010400 EV:0100079 BTO:0000269 MAT:0000526 it extracts water and salt from solid wastes before they are eliminated from the body[WP] NCIT:C12382 hindgut CALOHA:TS-0158 Wikipedia:Colon_(anatomy) XAO:0000243 FMA:14543 MA:0000335 TAO:0000706 posterior intestine large bowel In mammals, the colon consists of four sections: the ascending colon, the transverse colon, the descending colon, and the sigmoid colon[WP] A portion of the large intestine before it becomes the rectum. In mammals, the colon is the most part of the large intestine, excluding the vermiform appendix, the rectum and the anal canal. The posterior intestine has short longitudinally arranged epithelial folds which are similar to the colon of higher vertebrates.
