Abstract(s)

During a wide project carried out on the behavior and reproduction of the Atlantic lizardfish Synodus saurus in the Azores (NE Atlantic), specimens of the ectoparasitic isopod Anilocra physodes were discovered in various stomachs contents of these piscivorous predatory fish. This intriguing result allowed us to conclude for the first time that fish species can ingest their own parasites, which becomes doubly beneficial, since it releases them from para- sites but it is also a new food source.

RÉSUMÉ: Au cours de différents travaux menés sur le comportement et la reproduction du poisson lézard de l’Atlantique, Synodus saurus, aux Açores (Atlantique NE), des ectoparasites isopodes, Anilocra physodes, ont été découverts dans divers contenus stomacaux de ces prédateurs piscivores. Ce résultat intriguant nous a permis de conclure pour la première fois que des espèces de poissons peuvent ingérer leurs propres parasites, ce qui peut être doublement bénéfi- que pour eux, qui, tout en s’en libérant, disposent d’une nouvelle source de nourriture.
