They might just be saying that when you look *instead* at semi-aquatic mammals you don't usually see that technique.
The primary author DOES consider the mink semi-aquatic in the second study I mention and the sea otter aquatic.
Ferrets so like to hold their breath when they play with things put in deep water bowls (funny to watch through glass) that I wound up wondering if they were taught that something of interest is below water if they could get diving behavior, with what limitations, and with what effects on bone mass proportions.
We get so used to thinking of bone mass loss for medical reasons from possible hormonal ones such as perhaps from increased FSH output (caused by the same triggers of increased LH output, i.e. the same things that can lead to adrenal growth such as neutering or too little complete darkness, or both), and not usually the use-it-or-lose-it aspect except in extreme situations. I wonder, though, if domestic ferrets usually get too little upper limb exercise. It strikes me that superficially there could be some similarities of use between digging in situations where real weight is moved and the demands of diving, but I could be wrong.
