Penguin Genera
Six genera hold every living penguin. Genus is the closest thing to a family tree you can read at a glance — it predicts body plan, crest, and often breeding strategy before you know anything else about a species.
Every genus in the catalogue
6 entries across all 19 penguin species, ordered by how many species each one covers.
Single-species genuss
Each of these is held by exactly one species — usually a bird confined to one island group or one narrow niche. That isolation is normally the story.
