Fish bone is any bony tissue in a fish, although in common usage the term refers specifically to delicate parts of the non-vertebral skeleton of such as ribs, fin spines and intramuscular bones. Not all fish have fish bones in this sense; for instance, eels and anglerfish do not possess bones other than the cranium and the vertebrae.
Bones are rigid organs that form part of the endoskeleton of vertebrates. They function to move, support, and protect the various organs of the body, produce red and white blood cells and store minerals. Bone tissue is a type of dense connective tissue. Bones come in a variety of shapes and have a complex internal and external structure.

The inclusion of fish vertebrae, jaw bones, teeth, and other informative skeletal elements improves prey identification and quantification over otolith analysis alone. [24] This is especially true for fish species with fragile otoliths, but other distinctive bones, such as Atlantic mackerel (Scomber scombrus), and Atlantic herring (Clupea ...

Fish physiology is the scientific study of how the component parts of fish function together in the living fish. [2] It can be contrasted with fish anatomy, which is the study of the form or morphology of fishes. In practice, fish anatomy and physiology complement each other, the former dealing with the structure of a fish, its organs or ...
The involved elements include: the supraneural bones of the skull; modified neural arch bones, specifically the paired claustra and the scaphia; the intercalarium and the lateral processes; the tripus; the os suspensorium from the fourth vertebra; the parapophysis of vertebra number five including the vertebra itself, plus the vertebra's ...
The labyrinth organs, a defining characteristic of fish in the suborder Anabantoidei, is a much-folded suprabranchial accessory breathing organ.It is formed by vascularized expansion of the epibranchial bone of the first gill arch and used for respiration in air.
