Abstract
The correlation co-efficient (r) for the regression of various morphometric characteristics on total length ranged from 0.736 for the second dorsal (02 ) base to 0.997 for the standard length from snout to origin of dorsal Ic)be of caudal. The length (total) at birth ranges from 69 cm to 102 cm. The lengths at the age of 1, 10,20 and 30 years were estimated to be 102 cm, 269 cm, 341 cm and 366 cm respectively. The total life span is about 30 years.
