Do Animals Know When They’ve Eaten Enough?

This video explores how different species experience fullness, and why so many animals are built to completely ignore it.

We look at the physical stomach stretch receptors that wolves push to the absolute limit to survive a famine, and how fish like carp and goldfish lack this anatomical hardware entirely.

We also explore the chemical side of hunger, showing how grizzly bears hack their own biology by blocking hormonal signals to gorge for winter, while animals like squirrels use the forest floor as an external stomach instead of overeating.

For humans, being full means the meal is over. For the rest of the living world, eating is just a matter of survival.
