Resumo: An analysis of published data on oceanic seabirds diets, show the predominance of muscular cephalopods with superficial distribution in the oceanic layers, but also important are the gelatinous and ammoniacal species restrict to layers below 300 m from the surface. In principle, it could be not expected that deep-sea cephalopods are common prey for seabirds like several authors have been concluded. It is proposed in this study that an indirect source, important and easily attainable, have been appeared with the beginning of tuna longline operations. The habit to feed upon viscera of the fishes captured by tuna longliners, that discard the gut contents to the water, may explain the probable equivocal conclusions that deep dwelling cephalopods are natural prey of oceanic seabirds.

A princípio, não deveria se esperar que cefalópodes de profundidade fossem considerados presas comuns de aves marinhas oceânicas como reportados por muitos autores. É proposto neste estudo que uma fonte indireta, importante e de fácil obtenção, surgiu com o início das atividades dos barcos atuneiros que operam com espinhel. O hábito de ingerir restos de vísceras de peixes capturados em barcos espinheleiros pode explicar as prováveis conclusões equivocadas de que cefalópodes de profundidade são presas naturais de aves marinhas oceânicas.SciELO Brasil2011-03-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionhttps://www.biotaneotropica.org.br/BN/article/view/811Biota Neotropica; Vol. 11 No. 1 (2011): v11n1Biota Neotropica; Vol. 11 Núm. 1 (2011): v11n1Biota Neotropica; v. 11 n. 1 (2011): v11n11676-0603reponame:Biota Neotropicainstname:Instituto Virtual da Biodiversidade (BIOTA-FAPESP)instacron:BIOTA - FAPESPenghttps://www.biotaneotropica.org.br/BN/article/view/811/1488https://www.biotaneotropica.org.br/BN/article/view/811/1489Copyright (c) 2011 <span class="primary-color">Biota</span> <span class="secondary-color">Neotropica</span>info:eu-repo/semantics/openAccessVaske Júnior, Teodoro2021-10-02T04:37:59Zoai:biotaneotropica.org.br:article/811Revistahttps://www.biotaneotropica.org.br/v20n1/pt/PUBhttps://old.scielo.br/oai/scielo-oai.phpcjoly@unicamp.br || jasalim@unicamp.br1676-06111676-0611opendoar:2026-01-09T10:23:53.577271Biota Neotropica - Instituto Virtual da Biodiversidade (BIOTA-FAPESP)false
