Verwandtschaftsbeziehungen bei Pinguinen(Sphenisciformes)
Journal für Ornithologie, 1981Die Verwandtschaftsbeziehungen der Pinguine untereinander konnten bisher weder durch morphologische noch durch chemische Merkmale befriedigend geklart werden. Als weiterer Merkmalskomplex wird die Komposition der Burzelwachse von 11 Pinguinarten mit zumindest jeweils einem Vertreter samtlicher rezenten Pinguingattungen herangezogen.

Blood sampling technique in penguins (Sphenisciformes)
Veterinary Record, 1983The blood vessels in the flippers of members of the Sphenisciformes were studied with the aim of locating a suitable anatomical site for the collection of blood from this order. The optimal site was found to be the brachial vein on the ventral surface of the flipper. Blood samples were taken using this method from five different species.

Ordnung: Sphenisciformes – Pinguine
2021Pinguine beschreiben eine unverwechselbare Ordnung an Seevogeln, die an ein Leben in und am kalten Meer angepasst sind. Die groste Form ist der Kaiserpinguin mit 112–125 cm Korperhohe und 19–46 kg Gewicht. Der kleinste Vertreter ist der 35–45 cm grose und 0,5–2,1 kg schwere Zwergpinguin (del Hoyo et al. 1992).

Flightlessness and Long Bone Allometry in Palaeognathiformes and Sphenisciformes
Netherlands Journal of Zoology, 1996Palaeognathiformes and Sphenisciformes are the only two major taxa that have lost the capacity for flying. Nevertheless, the consequences of this flightlessness are completely different. While Palaeognathiformes are all running birds, Sphenisciformes are adapted to swimming. To study the morphology of leg and wing bones, length, sagittal and transverse

Skull morphometry of Pygoscelis (Sphenisciformes): inter and intraspecific variations
Polar Biology, 2006Morphological diversity of 47 pygoscelid skulls was tested empirically through geometric morphometrics approach. Using 14 landmarks, shape is analyzed independently of other aspects of the body form. The shape disparity within and between the three living species of Pygoscelis is explored as well as how the structure of the skull is related to food ...
