Anatomic Description

  • Mikhail Chebanov

As known, sturgeon has a range of anatomical peculiarities; those are significantly different from the anatomy of other fish species. This is most strongly manifested in the structure of following internal organ systems: digestive, excretory, hemopoietic, and reproductive ones.

The current chapter provides a brief description of the anatomy of inner organs of Siberian sturgeon. The anatomic features, that distinguish Siberian sturgeon from other species of the family, are presented in more details.

In particular this pertains to the structure of the digestive system (length of the intestine), peculiarities in formation of tissues and organs during early ontogenesis (the dorsal embryonic process corresponds to the long lobe of the pancreas), and the pancreas that in terms of its histology and functions differs cardinally from other fish species, but is similar to one in mammals.
