Anti-Predator Responses Of Squid Throughout Ontogeny, Carly Anne York

Biological Sciences Theses & Dissertations

Multiple sensory modalities and a complex array of escape behaviors have evolved as components of anti-predator responses in squids. The goals of this study include: (1) examine the role of the lateral line analogue and vision in successful predator evasion; (2) measure kinematics of escape jetting; (3) document how chromatic patterning, posturing and inking in squid change in response to predators; and (4) investigate escape jet hydrodynamics of squid. Given that squids undergo considerable morphological, ecological, and behavioral changes throughout ontogeny, the goals above were all investigated across different life history stages. To test the respective roles of vision and …
