Okay, as amusing as this is, I feel like I am missing something here. They know the feces shoot 30-40 cm off an edge - but the motivation for the research was because it might help zookeepers when planning enclosures? Or do they need to improve captive penguins' diets so that they can achieve the maximum pressure for their cloacal cannons? If the concern is zookeepers getting hit by flying feces, just avoid penguins perched on rocks with their backs to you, nigga.
