INTRODUCTION

Although many aspects of the biology of frogs and toads are reasonably well known, antipredator mechanisms have been largely overlooked or superficially treated. To date, there has not been a review of anuran defensive mechanisms. The purpose of this bibliography is twofold. One objective is to present a conprehensive list of published works dealing in any way with frog defensive mechanisms. To accomplish this, I have tried to review all references of frog antipredator mechanisms to verify that the reference is correct, to catalogue the different behaviors rnd mechanisms, and to list the species involved. Papers dealing t:ith biocheraistry and pharmacology of secretions have been e::cluded e::cept where they pertain directly to antipredator ov defensive mechanisms, I suggest those interested in biochemistry and pharmacology consult Lot: (1972"! and Paly and Witkop (1971) for references on these sub- jects. At tr.e end of the bibliography, there is a subject by reference listing. The second objective of this bibliography is to sti^^alate re- ferrch in the area of anuran antipredator m.echanisms. Much remains to be learned about anuran behavior and a bibliography hopefully will provide stimulation as vrell as a reference source, I would appreciate receivin;;; any additional information v:hich itiay have been excluded. Finally, T worild like to thank the following people xiho provided needed information: H-eorge Zug, Ron Heyer, Bruce Bury, Steve Busack, Ron Crombie, and Ron Altig, Bart Kavruck provided the cover illustra- tion of a I'aloula pulchra in its defensive posture,
