The DNA sequences of the mitochondrial cytochromeb gene of marine mammals (Cetacea, Pinnipedia, Sirenia) were compared with cytochromeb genes of terrestrial mammals including the semiaquatic hippopotamus. The comparison included 28 sequences, representing 22 families and 10 orders. The dugong (order Sirenia) sequence associated with that of the elephant, supporting the Tethytheria clade.
