Psammophis schokari is regularly seen and usually tries to escape quickly from human presence, but in this particular case, did not flee or regurgitate the prey. Once the prey was totally swallowed, the snake escaped quickly. Completion of the predatory action was apparently given priority by the snake over the potential threat coming from the human observers. Even if P. schokari is known to be mainly saurophagous, it is not surprising to observe an instance of ophiophagy. Both snakes are diurnal and can be syntopic. The fact that R. moilensis was a young snake Fig. 2: General view of the xeric habitat may explain the success of the attack. It is near the city of Figuig (eastern Morocco) highly unlikely that P. schokari exhibited a where the predation event took place. scavenger behavior in that case.
