Bivalves lack a central nervous system, but they have complex behaviors, because they live in dynamic environments. Scallops, for example, have eyes, which they use to navigate when swimming, identify predators, and make sense of their environment. Researchers found that presenting stimuli to scallops, they reached out to objects they saw to make sense of them with their feeling tentacles. #clamFactshttps://royalsocietypublishing.org/doi/10.1098/rspb.2021.1730
