It was observed that both lapillus and asteriscus could be used to determine the age of Carassius auratus , but the annulus on whole lapillus.

It is found that the three types of proteins in lapillus and asteriscus have different characteristics,and such differences may be responsible for different kinds of crystalline state in calcium carbonate.

The statolith microstructure may be observed by using the scanning electron microscope and the trace element can be detected by nuclear technology,and then the relationship between environmental factors and statolith length,its increments and trace elements concentration may be discussed.

Advances on using statolith to study age and growth of cephalopod

Age,growth and population structure of squid Sthenoteuthis oualaniensis in northwest Indian Ocean by statolith microstructure

Statolith in the cephalopod is an important source of ecological information, and mastering the morphologic features of the statolith is fundamental to fisheries biology.
