image: The researchers tested fiddler crabs using a crab treadmill that allowed the animals to walk naturally whilst being shown visual stimuli on a computer monitor. The crab would stop walking and freeze whenever it saw a stimulus. This material relates to a paper that appeared in the August 21st, 2019, issue of Science Advances, published by AAAS. The paper, by S.P. Smithers at University of Bristol in Bristol, UK, and colleagues was titled, "Parallel processing of polarization and intensity information in fiddler crab vision." view more
