Figure 1. – Non-destructive tissue sampling. A: (from top to bottom) dental probe, 1 mL insulin syringe MYJECTOR ® U-100 and specimen 19058 (standard length: 141.1 mm), male Oostethus manadensis; B: View of the brooding pouch and eggs of specimen 14964 (standard length: 113.23 mm), Coelonotus argulus, male; missing eggs correspond to the sample for DNA extraction; C: Scratching the inside via the urogenital papilla with the dental probe; D: Internal tissue sampling using the syringe via the urogenital papilla; E: State of urogenital papilla before sampling; F: State of urogenital papilla after sampling. Photos B to F are ventral views of the specimens; the arrow in B gives the orientation of the specimen in photos A, B; the arrow is C gives the orientation of the specimen in photos C-F.
