Penguins That Eat Crustaceans
10 penguin species in this guide eat crustaceans, including African Penguin, Eastern Rockhopper Penguin, Fiordland Penguin. Shared prey creates overlap, but it also exposes very different birds to the same ocean bottleneck.
Crustaceans 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.
