Penguins That Eat Squid

17 penguin species in this guide eat squid, including Adelie Penguin, African Penguin, Eastern Rockhopper Penguin. Shared prey creates overlap, but it also exposes very different birds to the same ocean bottleneck.

Squid matters because prey choice shapes dive depth, breeding success, and how badly a penguin suffers when the ocean changes. Two penguins can eat the same thing and still live completely different lives because prey only makes sense inside place, depth, and breeding rhythm.
