The liver functions are similar to those in
other vertebrates. In most teleost species, this
organ is more properly called the hepatopancreas
(contains exocrine pancreatic tissue which
can also be found in other areas in many fish).
Coloration can vary from pale tan to brown to
red, depending on species, diet, nutritional status,
and reproductive status. It is often one of the
largest/most visible organs in the anterior portion
of the coelomic cavity. In some species such
as koi and goldfish, the liver is intimately intertwined
with the intestinal tract.
