  • Growth rings (GR) in vertebral centra of 15 whale sharks, Rhincodon typus, four female (418–750 cm precaudal length), 10 male (422–770 cm), and one of unknown sex (688 cm), were examined using x-radiography. GR counts were made from scanned images and count precision was determined using the average percentage error index (4.19%) and the index of precision D (3.31%). In females, counts ranged from 19 GR (418 cm) to 27 GR (750 cm); in males from 20 GR (670 cm) to 31 GR (770 cm). Three mature… CONTINUE READING
