Pterosaurs that eat Bats

In Papua New Guinea, the ropen is said to eat fish or giant clams or dead human bodies, or even living humans, at least once in a while on the mainland, between Lae and Finschhafen, in Morobe Province. But in some parts of the world pterosaurs, very much non-extinct, are said to eat bats.

Whether with greater speed, or with greater team work, or with greater intelligence, predators must use an advantage. And whatever elevates the predator above the prey will also make it appear different, to some degree. Of course a careless glance may not reveal any difference between a shark and the fish it eats. Falcons and sparrows are small birds; ant lions and ants are small insects . . . nevertheless, many differences are subtle, allowing predators to run or swim or fly alongside prey . . .

To a biologist, bats and pterosaurs have only limited similarity, most obviously featherless-flying. But if they lived together, flying at night, could there be a predator-prey relationship? Yes.

Do Ropens, Extant Pterosaurs, Eat Bats?

In the summer of 2007, I learned that [some cryptozoologists] had found a new area to search for the cryptid we call “ropen” (I assumed it was still in Papua New Guinea). When I learned that they had seen many bats and apparent ropens flying, at night, over the same valley, at the same time, and that the sightings were throughout the year, it became obvious: The ropens must be catching bats. How could ropens be spending so much time flashing their ropen bioluminescent flashes throughout the year if they were not catching food? And what food could they be catching in the sky at night that would satisfy the hunger of a large pterosaur? Not insects.

Bat Eating Giant Bat

“One of the flashes took off from a big tree overhanging the river and made a kind of flashing coma turn. Many flashes were parallel to the river. . . . there were many fish . . . Prime hunting grounds for fish-eating birds. Only these things fish at night with bioluminescence . . .”

“This creature was huge . . . In the distance I perceived an object in the sky. At this point it was rather indistinct and wondering what it might be I watched it as it approached. . . . Within a minute or so it had reached our position and was about 250 or 300 feet above us . . . It did not  appear to be covered with feathers but had a leathery texture. Soon after it passed us it flew over a more brightly lit sports area  which  highlighted even  more the  leathery appearance . . .”
