Eudyptula Penguins
1 penguin species sit in the genus Eudyptula, including Little Blue Penguin. The useful question is not just who belongs here, but which body plan and breeding logic they still share.
Eudyptula includes the world’s smallest penguins, compact coastal birds that nest in burrows and often come ashore under cover of darkness. Little Blue Penguin shows the biggest expression of the body plan, while Little Blue Penguin shows where that same lineage is under the most pressure.

Open guideUnderstanding Eudyptula Penguins
The genus Eudyptula currently contains 1 recognized species: Little Blue Penguin. All Eudyptula penguins share a common ancestor and retain a recognizable body plan, but the similarities go deeper than appearance. Shared lineage means shared physiology — similar feather density, comparable diving mechanics, and overlapping metabolic strategies for coping with cold water and long fasts.
Where the species diverge tells you what environment does to a shared blueprint. Little Blue Penguin, the largest in the group at up to 33 cm, has pushed the body plan toward extreme size and endurance. Little Blue Penguin, at up to 33 cm, represents a more compact expression adapted to different breeding conditions and food access.
Across the genus, diet centres on small fish, squid, crustaceans, though the proportions and foraging depths vary by species and season. These penguins are found across New Zealand, Southern Australia, which means the same genetic toolkit meets very different ocean temperatures, predator communities, and human pressures.
Conservation status within the genus ranges from Least Concern. Little Blue Penguin faces the most acute pressure, a reminder that even closely related species can sit at very different points on the survival curve depending on where they breed and what they eat.
Frequently asked questions
Which penguins belong to the genus Eudyptula?
Little Blue Penguin all sit inside the Eudyptula genus, which means they share part of the same evolutionary frame even when their lifestyles diverge.
What is the largest Eudyptula penguin?
Little Blue Penguin is the largest Eudyptula penguin here, reaching up to 33 cm tall.
Why compare penguins by genus?
Genus lets you compare inherited design before outside pressures start rearranging the story. It is the cleanest way to see which traits belong to lineage and which belong to environment.
