Chromosome analyses were carried out on bone marrow cells from three elephant seal pups (Mirounga leonina), a species characterized by a 2n = 34 chromosome number. Arm ratios for the different chromosomes were calculated to facilitate the classification of chromosomes into groups. The karyotype of the southern elephant seal differs from other reported 34-chromosome phocids in the morphology of the Y chromosome and in that of one of the autosomal chromosome pairs.
