| Each species pertains to a given functional niche, depending on its relationships with others species and its interactions with the abiotic environment. Understanding inter-specific interactions is critical to know and predict ecosystems' structure, functioning and dynamics, but also their response to anthropogenic impacts. Predator-prey relationship is one of the main biotic interactions as it both determines the survival of the prey and the predator and is the keystone of food webs. Unraveling the determinants of predator-prey relationships or, in other terms, the reason why a given predator catches a given prey is therefore of primary importance. Fishes are characterized by a remarkable diversity of shapes which can be associated by their feeding and... |

| By covering 80% of Earth, the global ocean is the most spread ecosystem in the world. Human activities (pollution, fisheries…) have huge impacts on both oceans and marine life. Despites overfishing and intense maritime transport, many fish species remain in the English Channel. A major challenge in biological research is to comprehend and facilitate the emergence of body shape in fishes for understanding how these organisms may respond and persist in complex and multiple environments with predictable and unpredictable perturbations. Body shape in fish is conditioned by several developmental paths and functions depending on multitude behaviours. Fishes body morphology varies in every species and in some cases had been shown to influence their occurrence,... |
