Ideally it will get close to its prey and use its neck to further close in, with the fast mechanism serving to allow for it not to require to open its Jaws before, as their insides are brightly colored (in its strategy, the neck substitutes the suction force it would have in the water, which, like Charisturcear already noted, would not be useful here, unless the atmosphere was as dense as water). The reason for choosing this mechanism is to its potential to develop more power in the jaw thanks to more attachment for muscles. | |

| Jun 17, 2020 at 4:59 | comment | added | Charisturcear | Another Little problem could be, in water this high speed of opening and closing creates a suction force, which reduces the problem of moving the head to get the prey further. In air, even with a denser atmosphere, it does not (it is to small to have an Impact). So you don't just need the speed of jaw-opening and -closing, you also have to move the head in direction of the pray in this time. That reduces efficiency of this build by far. I still think it's possible, but am not realy sure if it is that usefull. | |

However, this mechanism would be very bulky and limit range of motion in the neck. As an aquatic creature, articulation of the neck is not important and really didn't evolve in creatures until much later, which terrestrial animals rely on. You may need to address if neck articulation is important to your creature first to know if this evolutionary feature is needed. | |
