An observation of predation by a Yellow-spotted Monitor (Varanus panoptes panoptes) on a venomous Lesser Black Whipsnake (Demansia vestigiata)

We report on an observation of a large Yellow-spotted Monitor (Varanus panoptes panoptes, Varanidae) successfully predating upon a venomous Lesser Black Whipsnake (Demansia vestigiata, Elapidae). The medium-sized elapid snake managed to bite the monitor several times before being consumed. The monitor displayed signs of neurotoxic envenoming, including hind limb lethargy, before making a rapid and full recovery. This observation corroborates research findings on varanid resilience to neurotoxic binding and cephalic osteoderms as a defence against venomous prey.
