In contrast, the manatee has very low body fat. Its shape is due to size of its lungs.
Interesting. So low “butter fat” kept it from being wiped out as a food source perhaps. An evolutionary plus. Still can’t keep away from propellers, not the brightest bulbs.
I remember reading hunting magazines as a kid. Ads for the new nylon .22 by Remington. The full page ad showed a commercial fisherman shooting a seal eating a fish in his purse seine net. Back then you could. Jimmy Carter banned the killing of all sea mammals and now if you ply the waters in many states pinipeds can be seen blocking all docks and crowding onto people’s boats and such. They have decimated the fishing in certain areas. ( Of course sirenians are slower to increase in numbers and will need a longer moratorium)
It’s what happens when emotions cloud the intellect. Nothing wrong with stewardship. You keep populations of some things moderated and strategically removed surpluses where necessary.
