I privately got a question of why I was not going to put up the swimming st=
udy, so I guess I'd better clarify that I just figured it was too OT. On s=
econd thought, though, I have to agree with that correspondent that it does=
count as behavioral information so isn't OT.
So, here is the abstract:

Energetics of swimming by the ferret: Consequences of forelimb paddling.

The domestic ferret (Mustela putorius furo) swims by alternate strokes of t=
he forelimbs. This pectoral paddling is rare among semi-aquatic mammals. Th=
e energetic implications of swimming by pectoral paddling were examined by =
kinematic analysis and measurement of oxygen consumption. Ferrets maintaine=
d a constant stroke frequency, but increased swimming speed by increasing s=
troke amplitude. The ratio of swimming velocity to foot stroke velocity was=
low, indicating a low propulsive efficiency. Metabolic rate increased line=
arly with increasing speed. The cost of transport decreased with increasing=
swimming speed to a minimum of 3.59+/-0.28 J N(-1) m(-1) at U=3D0.44 m s(-=
1). The minimum cost of transport for the ferret was greater than values fo=
r semi-aquatic mammals using hind limb paddling, but lower than the minimum=
cost of transport for the closely related quadrupedally paddling mink. Dif=
ferences in energetic performance may be due to the amount of muscle recrui=
ted for propulsion and the interrelationship hydrodynamic drag and interfer=
ence between flow over the body surface and flow induced by propulsive appe=
ndages.

Thanks for the correction! You were right!
Another friend pointed out an excellent point: that the amount of subcutan=
eous fat may also be a consideration. Minks tend to have a load of that.
