This summer, Kero continued our work testing the snail navigation behaviour towards food sources.   His experiment focused how the animals performed in the dark but with water flow.  That meant he had to first construct a cover in order to block any light from reaching the flow tank.  Then 54 trials across 3 different treatments, comparing responses to tasty food (to a snail) to two control conditions.  Then analysis of the video data began: transforming all the trials into videograms and tracking the different snails throughout out the trials.
