The skull morphometrics of adult male Antarctic fur seal, Arctocephalus gazella (Peters, 1875) and South American fur seal, A. australis (Zimmermann, 1783) were investigated using a collection of 45 and 38 skulls, respectively. Eighteen measurements were taken for each specimen. Comparative univariate and multivariate statistical analyses included standard statistics, one-way analysis of variance, principal component analysis and discriminant analysis. Individual variation was relatively high for some variables, as expressed by the coefficient of variation. Skulls of A. gazella were larger than those of A. australis for all but two variables: squamosal jugal suture and rostral length. Both species differed significantly as shown by both univariate and...

Anomalias e patologias dentárias em Arctocephalus G. Saint-Hilaire &amp;amp; Cuvier (Pinnipedia, Otariidae) da costa do Rio Grande do Sul, Brasil
Provedor de dados: Zoologia
Autores: Drehmer,César Jaeger; Ferigolo,Jorge.
The studied species were Arctocephalus australis (Zimmermann, 1783) and Arctocephalus tropicalis (Gray, 1872), (five specimens of each one). Anomalies were discussed under the light of theories which relate the ancestry of pinnipeds with the Ursidae; as well as concerning the evolutionary trends supposed for the Otariidae. Pathologies were related to alimentary and reproductive habits.
