“When bottlenose dolphins swim — at a cruising speed around six miles an hour or a sprinting speed about twice that fast — they are constantly fighting against the water’s drag, which only gets worse as they swim harder.
Shawn R. Noren, a marine biologist at the University of California, Santa Cruz, set out to find how much extra drag would be experienced by a specific, aerodynamically disadvantaged subset of the dolphin population: adult females nearing the end of pregnancy.
…Pregnant dolphins also swim differently, making shorter but more frequent strokes. And the growing fetus stretches out the mother’s muscles, probably making it more difficult for her to thrust her tail up and down.”

What can we swimmers learn from this? How does it relate to stroke rate and distance per stroke?
Through no fault of my own, I find that I have a less than optimal hydrodynamic profile. I wouldn't say I look like a pregnant dolphin, but opinions may vary. Should I shorten my stroke and increase my stroke rate to compensate for this unfortunate circumstance?

In my opinion, this is the most interesting new discussion here in quite a while.
Kudos to Djacks for bringing it to our attention.
I tend to agree with Ande that the most likely applicable suggestion would be smaller, more frequent SDKs. Alas, the older we get, and the more pregnant we look, the harder it is for many of us to fire off a frenzy of tight, quick SDKs without triggering back spasms and the like.
Perhaps the ultimate solution would be for the Spanx Corporation to get into the manufacturing of swim wear? Smoosh those virtual babies back inside the abdominal cavities where they belong!
