ASYMMETRY ANALYSIS STUDY ON Callionymus margaretae REGAN, 1906 COLLECTED FROM THE ARABIAN SEA COASTS OF OMAN

Abstract

Asymmetry analyses have been carried out for some bilateral characters of Callionymus margaretae Regan, 1906 collected from the Arabian Sea coasts of Oman. The results showed that the level of asymmetry of the character postorbital length was the highest among those asymmetry values obtained for the remaining characters studied. The lowest value was that for the head length. An increasing trend in the asymmetry value with fish length is also obtained for preorbital and postorbital lengths. The possible cause of the asymmetry in this species is herein discussed in relation to different pollutants and their presence in the area.
