Herein, we report on our laboratory study in March and April of 2012, where we immobilized early life stages (tadpoles and recently metamorphosed frogs) of American bullfrog, Lithobates catesbeianus, and Southern leopard frog, Lithobates sphenocephalus, using low-voltage electrical current.
1--Peak power density thresholds resulting in immobilization of tadpoles of American bullfrog, Lithobates catesbeianus (AB), and Southern leopard frog, Lithobates sphenocephalus (SLF), standardized to 100 [micro]S/cm ambient water conductivity using 4 pulse frequencies (15, 30, 60 and 120 Hz).
Eumeces (Plestiodon) farciatus), 3 species of amphibians (including Lithobates sphenocephalus, Litho bates catesbieanus and Notophthalmus viridescens), and 4 species of turtles (including Graptermys geographica, Chrysemys picta, Pseudemys floridana and ApaIone spinifera).

Species that tested negative included Lithobates sphenocephalus utricularius, Anaxyrus terrestris, Anaxyrus americanus, Hyla cinerea, and Hyla versicolor/chrysoscelis.
Thus, we explore here the impact of missing labial teeth on the feeding performance of tadpoles of the Southern leopard frog (Lithobates sphenocephalus [ = Rana sphenocephala] Cope, 1886).
Removing a single row of labial teeth (P-3) in Lithobates sphenocephalus tadpoles alters their feeding kinematics, changes their foraging efficiency, and reveals some constraints missing teeth have on feeding.
