Lateral‐line organs in some teleosts: Cirrhina mrigala ham. Buch. (Cyprinidae), Ophicephalus (Channa) punctatus Bloch (Channidae) and Gobius striatus Day (Gobiidae)

Abstract

The structure and location of "ordinary" lateral-line organs of the fry and the adult specimens of three teleosts, Cirrhina mrigala, Ophicephalus ( C h a n n a ) punctatus and Gobius striatus, have been studied and the results have been discussed. The stalked condition of surface organs, described for G. striatus, i s a new feature reported for the first time in this communication. An attempt has been made to classify "ordinary" lateral-line organs on morphological grounds, especially the group of "pit organs," taking into consideration the orientation of the neuromast concerned in relation to the surface of the adjacent skin, the basement membrane, the dermis and the thickness of the surrounding epidermis.

“…To standardize the terminology, we have devised a classification scheme, similar to that used by Srivastava and Srivastava (1968), that is based on the relationship between the neuromast, the dermal and epidermal layers, and the basement membrane between them. Several types of superficial neuromasts are recognized, though some types may represent ontogenetic stages in the development of adult neuromast morphology, as well as an adult condition ( Fig.…”

“…Called type A by Srivastava and Srivastava (1968), this superficial neuromast is the general type found in larval fish (Pehrson 1945;Srivastava and Srivastava 1968).

These have been called type B (Srivastava and Srivastava 1968), cryptes sensorielles (Budker 1958), andfossettes sensorielles (Szabo 1963) and probably represent an ontogenetic stage in canal neuromast formation in larval fish (Allis 1889;Johnson 1917) (Fig. These have been called type B (Srivastava and Srivastava 1968), cryptes sensorielles (Budker 1958), andfossettes sensorielles (Szabo 1963) and probably represent an ontogenetic stage in canal neuromast formation in larval fish (Allis 1889;Johnson 1917) (Fig.…”
