I will present the results of recent work studying the dependence of specific morphological features on various measures of galaxy environment. These studies examine not only the presence of key morphological features, but also quantify their characteristics, e.g. the number and winding tightness of spiral arms, using large, statistically powerful samples. I will show how we are able to quantify the prevalence and properties of particular galaxy types, some of which are rare, but which are all important for understanding the evolution of the galaxy population. This work is based on data from Galaxy Zoo 2, an online citizen science project which has involved many thousands of volunteers in the task of visually classifying over 250,000 galaxies from the Sloan Digital Sky Survey. Our results depend on the combination of large sample and robust morphological measurement that can currently only be obtained by utilising citizen science.
