Yeah, that's probably a good way to hunt and as the Plesioth uses those high pressure water beams to attack hunters on land while it is in water it could use it to hunt monsters on land or in air.

But I think Vespoids and Bnahabras would rather be torn apart than a useful prey so I guess it does it like in this photo that it tries to get the Neopterons in flight by jumping out.
