Estimation of Sexual Maturity Based on Morphometrics of Genital Organs in Male Northern Fur Seals, Callorhinus ursinus

It's not always possible to obtain samples from dead male pinnipeds that are fresh enough to determine the histological characteristics of spermatogenesis and their stage of sexual maturity. We propose that the morphometrics of genital organs of northern fur seals, Callorhinus ursinus, can be u...
