But the fact that it spends more energy, and it is less efficient, should be interpreted as a sign that something is wrong, isn't it? The gestures are powerful

But the fact that it spends more energy, and it is less efficient, should be interpreted as a sign that something is wrong, isn't it? The gestures are powerful but the fish does not advance a lot.
Limping on one leg is a more extenuant exercise precisely because you need (and show) more power (and that is less sustainable). I don't think a lion would see it as a warning signal!
- ibnjmn 9y agoI know next to nothing about submarine dynamics, but I am an RC plane pilot, and it looks to me like this fish swims in a constant stall. If it was a plane, I'd be inclined to say that its center of gravity was too far back. The video states that it can control its own bouyancy, yet it looks like it's constantly fighting to swim level instead of sinking. If it could achieve a neutral bouyancy then I bet it would glide along much more like a real fish.
