For those of you who've seen my other questions about the Chomping Eggs, please bear with me. This new creature is similar but named a Dropper (reasoning below). It has two wings and an egg-shaped body covered in a calcareous shell, with an eye on the front and back.
The bottom of the egg is split in two by a jagged seam (the cutting edge/teeth of this thing's mouth), forming a pair of mandibles. These mandibles each have an eye, and there is a secondary mouth within the mandibles, a ring surrounded by tentacles.
It's called a Dropper because it's entire hunting strategy is to use its many eyes to fly through the air, position itself above some tasty-looking animal, then tuck in its wings and fall onto the unfortunate prey with an open mouth. The mandibles clamp down to prevent escape, and the tentacles force prey down the hatch. It's not exactly huge, so it can only eat things like pigeons, turtles, squirrels, and the head of some unlucky sap who doesn't realize that shadow overhead is bad news.
I'm looking for a plausible explanation for this creature, and my criteria is:
A) clarity B) believability
