Description

technical field

[0001] The invention belongs to the field of aquatic science, and mainly relates to a method for grinding and preserving cephalopod otolith slices. Background technique

[0002] Cephalopods are an important group of molluscs, which not only have high economic value, but also occupy an important position in marine ecology. Cephalopod otoliths, like fish, are good information carriers, and they have two basic conditions. One is that the information input is stable; the other is that the input information can be well stored.

[0003] Otolith deposition is irreversible, and its growth occurs throughout the entire life process, and reabsorption of otoliths occurs only in extreme hypoxia. Otoliths are a pair of hard tissues located in the balance sac and play a balancing role. They are cephalopod acceleration sensors and contain a lot of biological and ecological information. They are vividly called life recorders. It can reveal hatching body length of cephalopo...
