RESUMEN
New morphological, morphometric and scanning electron microscopy data of a nematode of the family Anisakidae, recovered from a specimen of Kogia sima, a cetacean that died off the northern coast of Brazil, are presented in this paper. Morphological features such as the violin-shaped ventricle and short and equal spicules, as well as the distribution of post-cloacal papillae and specificity for the definitive host (Kogiidae cetaceans) demonstrate similarity to Skrjabinisakis paggiae. This research records Kogia sima and S. paggiae on the estuarine coast of Pará, northern Brazil.

Abstract New morphological, morphometric and scanning electron microscopy data of a nematode of the family Anisakidae, recovered from a specimen of Kogia sima, a cetacean that died off the northern coast of Brazil, are presented in this paper. Morphological features such as the violin-shaped ventricle and short and equal spicules, as well as the distribution of post-cloacal papillae and specificity for the definitive host (Kogiidae cetaceans) demonstrate similarity to Skrjabinisakis paggiae. This research records Kogia sima and S. paggiae on the estuarine coast of Pará, northern Brazil.
Resumo São apresentados, neste trabalho, novos dados morfológicos, morfométricos e de microscopia eletrônica de varredura de um nematoide da família Anisakidae, recuperado de Kogia sima, um cetáceo que veio a óbito na costa norte do Brasil. Características morfológicas, como o ventrículo em forma de violino, espículos curtos e iguais, além da distribuição de papilas pós-cloacais e especificidade pelo hospedeiro definitivo (cetáceos Kogiidae) demonstram similaridade a Skrjabinisakis paggiae. Esta pesquisa registra Kogia sima e S. paggiae na costa estuarina paraense, norte do Brasil.
