BALDASSIN, P., SANTOS, R. A., CUNHA, J. M. M., WERNECK, M. R., GALLO, H. Cephalopods in the diet of Magellanic penguins (Spheniscus magellanicus, FORSTER, 1781) Found on the cost of Brazil. Marine ornithology. v.38, p.55 – 57, 2010.
The present study describes the occurrence of cephalopods in the stomachs of 16 specimens of S. magellanicus found on the Brazilian coast in 2006. The specimens examined were live juveniles found on the northern coast of the state of São Paulo and the southern coast of the state of Rio de Janeiro. All specimens necropsied contained cephalopods. A total of 502 beaks were found, originating from three species of cephalopods, the most abundant of which was the pelagic octopus Argonauta nodosa Lightfoot, 1786 (95.8% of beaks), followed by the squid Loligoplei Blainville, 1823 (3.0%) and the sepiolid Semirossia tenera Verril, 1880 (0.2%) (Table 1). Among the material analyzed, five (1.0%) of the beaks from squids were only identified to the family level (Loliginidae).
