You are hereAnatomy of an acanthomorph / Visceral anatomy
Let us examine the visceral anatomy of a European perch (Perca fluviatilis, Percidae) :
The following images havebeen taken on a frozen and sawn female European perch (sections and images by C. Guintard (Oniris, Nantes)).
scale bar: 5 cm.
Have a look then in a nototheniid, Notothenia coriiceps, collected in Terre Adélie :
In acanthomorphs, kidney plays two main functions. Blood filtration and urine production are done in the posterior part of the kidney. The cephalic (=anterior) part of this organ has an haematopoietic role, and is where blood cells (red and white cells) are produced. For this function, the kidney of acanthomorphs is similar to the bone marrow of mammals. In acanthomorphs and teleosteans, this cephalic region or the spleen are used to collect cells for cytogenetic studies.
