Animal eyes are exquisitely well adapted to support species-specific vision, which differs greatly across the vertebrate lineage. Accordingly, understanding retinal computations fundamentally requires understanding how the animal in question uses its eyes, and what aspects of the natural visual world are of particular behavioural relevance. To contribute to our growing understanding of animal visual ecology, we therefore complement our core physiology work with field work where we visit our animal’s natural habitat and map their visual environment using custom built camera and scanner systems. This in turn allows us to relate our physiology and behavioural data to their natural purpose.

Video: Paramecia (larval zebrafish prey) in a naturalistic tank placed in the midday sun, with “yellow” filter (left) and UV filter (right). Paramecia are much easier to spot in the UV channel as bright moving dots.
