Marine mammal function and behaviour

Te Papa researcher: Felix Marx

Together with my collaborators from Australia, Europe and Japan, I study the diversity, function and evolution of marine mammal behaviour, from feeding to swimming and communication. I am particularly interested in the origin of filter feeding in baleen whales, suction feeding in whales and seals, tooth sharpness and function, and the shape and use of the forelimb flipper.

Investigating these topics often requires an interdisciplinary approach and the use of a broad range of techniques like 3D scanning, computational fluid dynamics, and even behavioural observations of live animals.
