Morphology, ontogenesis and mechanics of cervical vertebrae in four species of penguins (Aves: Spheniscidae).
16 pages International audience Penguins (Aves: Spheniscidae) are pelagic, flightless seabirds, restricted to the southern hemisphere (Antarctic and sub-Antarctic areas, New Zealand, Australia, and nearby islands, as well as parts of South America and South Africa).
