Figure 8. Pictures of the preserved DNA voucher tadpole of Gephyromantis sp. aff. blanci (ZSM 649/2008). (A) Dorsal view; (B) lateral view; (C) oral disc. Note that anterior limbs have been partly removed as tissue sample for DNA barcoding.
Figure 7 in Nidicolous tadpoles rather than direct development in Malagasy frogs of the genus Gephyromantis
Figure 7. Larval development of Gephyromantis sp. aff. blanci from Ranomafana. Drawings were made on the basis of photographs of living specimens and are not to scale. Time is given as days after collection of the clutch; the actual time since egg deposition is unknown. Note in the photographs in ventral view that the larvae in comparatively early stages appear to have a developed mouth with jaws (no tadpole-like oral disc).
