Hi All
I have  aquestion and I would like to know the answer from the interested people.
We are all know that in fish head there are three sets of otolith called, Sagitta, Asteriscus and lapillus. In all teleosts except the members of the families Cyprinidae and Siluridae, Sagitta is the largest and carry an ornamentation on its surface. In Cyprinidae, Sagitta is the very small and Asteriscus is the largest, while in Siluridae, Lapilus is the largest.
Could anybody explain to me why such differences occur.
Regards
