Are penguins keystone species

Penguins are not typically classified as keystone species, but they play important roles in their ecosystems. They serve as indicators of ocean health, as their population dynamics can reflect changes in marine environments. Additionally, their foraging habits influence the distribution of prey species, and their guano contributes nutrients to the ecosystem. However, the term "keystone species" is more commonly applied to species that have a disproportionately large impact on their environment relative to their abundance.
