The Behavior and Ecology of Herotilapia multispinosa (Teleostei, Cichlidae)

Morphological characteristics of Parsi cichlid Iranocichla persa (Teleostei; Cichlidae)

To provide more morphological data of I. persa, in this study, morphological characteristics along with scales and otolith were studied. Fish samples were collected from Khorgo spring and transferred to the laboratory. Fish were classified into three class sizes based on standard length. Based on the results, the size of the first class was different in 12 relative traits but did not show a sig...

Alternative tactics of male compensatory behaviour during parental care in Cichlasoma octofasciatum (Teleostei: Cichlidae)

Hair cell heterogeneity in the goldfish saccule.

A set of cytological studies performed in the utricle and saccule of Astronotus ocellatus (Teleostei, Percomorphi, Cichlidae) identified two basic types of hair cells and others with some intermediate characteristics. This paper reports on applying the same techniques to the saccule of Carassius auratus (Teleostei, Otophysi, Cyprinidae) and demonstrates similar types of hair cells to those foun...
