Abstract: For amphibians, non-lethal sampling methods have been developed and evaluated for only two of the three extant orders, with the limbless caecilians (Gymnophiona) thus far overlooked. Here we assess 16 different methods in five caecilian species representing five families with differing morphologies and ecologies. DNA was successfully extracted and amplified for multiple genetic markers using all tested methods in at least some cases although yields are, unsurprisingly, generally substantially lower than for DNA extractions from (lethally sampled) liver. Based on PCR performance, DNA yield and sampling considerations, buccal swabs, skin scrapes, blood pricks and dermal scalepocket biopsies performed the best.
