Sea lions mesmerize me. This one was swimming loops in its pool, and it's hard to imagine anything more aerodynamic when they pull in their front flippers and glide underwater before surfacing. I could watch all day.
NOTE: Yes, hydrodynamic is the proper term. But outside of a fluid dynamics class who's ever heard of that?

Hydrodynamic: literally used it in a sentence (in a text message) two days ago.
Meooooow!! Kitties know...
Jealous?
(I am)
Cecil: "I am Springfield's chief hydrological and hydrodynamical engineer!"
Sideshow Bob: "Hydrological *and* hydrodynamical? Talk about running the gamut..."
*sigh* nobody EVER pays proper attention to atomic Bose-Einstein condensate quantum hydrodynamics ...
A hydrodynamic hydrophile with hydrophobic skin?
Anyone with a modicrum of education and experience with English?
You have, it would seem 🙂
Thanks for triggering my college fluid dynamics PTSD. Stokes! Reynolds!
Aaaaargh!
A. Aerodynamic IS hydrodynamic. A fluid is a fluid.
B. Nothing beats the sight of a penguin flying underwater. But seals do come pretty damn close.
Confinement. Swimming circles in a prison-pool. Anyone else feel terrible about this? Ever since I watched The Truman Show, I get sad at the thought of a zoo or an aquarium.
Can someone enlighten me about the positives that counterbalance the misery these prisoner/animals endure?
