Anomalies in fishes are not uncommon and have been reported from different parts of the world from time to time. This study presents a record of an abnormal male and an abnormal female torpedo trevally, Megalaspis cordyla, L. collected from Ormara, Balochistan in August 2008 and from Karachi Fish Harbour (KFH) in October 2013 respectively. Gross morphometric measurements were taken. The specimens were compared with 293 specimens (59.7% females and 40.27% males) of M. cordyla and found that the key characters were similar whereas, both of the abnormal specimens were lacking anterior anal spines and anal fins which are normally present in M. cordyla. The X-ray result indicated that the specimen collected from Ormara was a congenital deformity and in other specimen collected from KFH indicates that the spines and fins were not congenitally absent although there was some indication that the deformity may be result of an injury that might have occurred during juvenile period.
