Resumo: | This study describes an interespecific association between spinner dolphins (Stenella longirostris) and the fishes black durgon (Melinchthys niger), sergeant major Abudefduf saxatilis) and jack (Carangoides sp.) in Dolphin's Bay, Fernando de Noronha Archipelago (3º51'S; 32º25'W) Brazil. The observations (n=17) weremade between June and September 1985 through the use of the snorkelling, totalling approximately 76 hours. When the spinner dolphins entered the bay after their night feeding period, they frequently defecated a light brown semiliquid fecal material, and this was immediately swallowed by the three fish species above, which are exclusive residents of the reefs. The interaction most commonly observed occurred with black durgon (55,7%), followed by sergeant major (28,3%) and jack (16%), all of which are opportunistic feeders. These interactions decrease in number throughout the morning as does the number of times the dolphins defecate. The spinner dolphins were not observed preying upon these fishes, althought on some occasions juvenile dolphins were seen chasing jacks, displaying behaviour which was clearly that of play. |

As observações (n=17) foram realizadas entre os meses de junho e setembro de 1985 através de mergulho livre totalizando aproximadamente 76 horas. Quando entravam na baía, após o seu período de alimentação noturna, golfinhos-rotadores defecavam com frequência um material semi-líquido de cor castanho-claro que era imediatamente ingerido pelas três espécies de peixes exclusivamente recifais acima citadas. A interação mais comumente observada ocorreu com o cangulo (55,7%), seguida pelo saberé (28,3%) e xixarro (16%), espécies de hábitos alimentares oportunistas. Essas interações vão decrescendo ao longo da manhã, quando os golfinhos passam a defecar com menor incidência. Não foram observados golfinhos-rotadores predando esses peixes, porém, em algumas ocasiões, juvenis perseguiram os xixarros em uma clara atitude de brincadeira.Universidade Federal de Santa Catarina1998-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/21937Biotemas; v. 11 n. 1 (1998); 127-1322175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/21937/19897Copyright (c) 1998 Liliane Lodihttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessLodi, Liliane2022-11-18T13:12:15Zoai:periodicos.ufsc.br:article/21937Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2022-11-18T13:12:15Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |
