I mean previously it stated that these were the two most dimorphic species. I’m guessing that due to the variance in body weight of the animals, it’s not that easy to say that they are more dimorphic than other species, because that depends upon the variable body mass of the animals. But it’s certainly a notable quality of polar bears and elephant seals that there can be such a huge difference, even if that difference grows and shrinks at different times of year.
