such as bones; food material after all the nutrients have been extracted, for example

tract; and dead or excess gut bacteria and other endosymbionts.;

Uberon Taxon note : In the lungfish, sharks and rays the rectum opens into the cloaca which also receives
wastes (urine) from the kidneys and material from the reproductive organs. In bony
fish the rectum reaches the outside environment through the anus, which is normally
situated just in front the urinary and reproductive openings. However in some fish
the digestive tract may be curled back on itself, and in the Electric Eel (Electrophorus
electricus) the anus is situated in the fish's throat. -- http://www.earthlife.net/fish/digestion.html;
