Insights into the diet of a poorly known species: pygmy killer whale Feresa attenuata from Cape Verde, West Africa
Despite having a worldwide distribution in tropical waters, knowledge on pygmy killer whales Feresa attenuata, including diet, is poor, with only a few studies carried out to date. The presence of otoliths and beaks in stomachs that have been examined indicate that the diet of F. attenuata includes...
