Summary

The ability of the Common ToadBufo bufo (L.) to distinguish between a worm-like and an antiworm-like (e.g., a bar at right angles to its direction of motion) moving stripe is not generally altered by movement dynamics, such as velocity of motion or by particular movement patterns—so far as has been investigated. A small square stimulus, however, with its “indifferent” shape is more attractive as prey for the toad when displaced in a stepwise manner, rather than moved at corresponding continuous (constant) velocity. Step frequencies of 1 to 2 cps were found to have optimal releasing values.
