Hypercarnivore
- Hypercarnivore
-
Un hypercarnivore est un animal dont plus de 70% de son régime alimentaire est composé de viande provenant de vertébrés, le reste étant constitué de nourriture non animale telle que des champignons, des fruits et autres produits végétaux[1],[2].
Par exemples des dauphins, les aigles, les serpents, les marlins, la plupart des requins et des invertébrés comme les pieuvres et les étoiles de mer[réf. nécessaire].
De plus, ce terme est également utilisé en paléobiologie, afin de décrire les taxons animaux ayant une augmentation de la composante de glissement de leur denture en rapport avec une fonction de broyage[2].
Les hypercarnivores ne sont pas forcément des superpredateurs. Ainsi les saumons sont exclusivement carnivore, mais restent des proies à toutes étapes de leur cycle de vie.
