bone
As bone is called bone, more delicate parts of the skeleton by bony fish such as fins and fin rays , but especially the Bindegewebsverknöcherungen transversely rearwardly inclined to the ribs between the muscle segments are and no contact with the spine have.
Zoologically only these connective tissue ossifications are called bones. Recently they only come to the Teleostei (but not to all: eel and monkfish, for example, are boneless). There are several series (Epineuralia, Epicentralia, Epipleuralia and Myorhabdoi), the delimitation of which - even to the ribs - is still uncertain. The bones serve to support the core muscles without restricting their mobility. The epineural bones are z. B. with cyprinids often "annoying" (they can be branched in tufts!), But also the epipleuralia can be divided lengthways or crossways. The bones are in their variety z. Z. Subject of research.
In the case of edible fish , bones and ribs are removed before eating . In most cases, swallowed bones are harmless. Due to the narrow, tapering shape, however, there is the possibility that they could get caught in the esophagus or trachea . The bone must then be removed by a doctor.
