“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?

I doubt that what works for a dolphin would work for me. Actually, when I weighed more I found the added buoyancy annoying, my balance was off. I much prefer being thinner. At my current weight, I have close to neutral buoyancy.
But dolphins are built differently. I have long arms and legs. They have flippers. My body length is about 1/3 of my total length, dolphins are almost all body length.
And that doesn't explain why my Siberian Husky can outswim me with her head and tail way out of the water. Maybe I should dog paddle.
