Bick et al. describe a novel way of testing their hypothesis that an invasive predatory snail fails to drive to extinction a native, threatened non-predatory snail because both have different tolerance ranges for exposure to sunlight. They test it by developing a miniature light sensor, small enough to be carried by these snails on their shells.
