A more complete description from here:
"It was about three feet and half high, with a head like a collie dog and
Now, look at this creature:
His name is Hypsignathus monstrosus, the hammer-headed fruit bat. When science is calling you a monster, you know you're weird. Only the males have the namesake heads, but damn if they do not look like the Jersey Devil's little brothers!
Hammer-heads are big enough bats to warrant a cryptid legend. A male hammer-head's wingspan can be up to 970 millimeters. That's almost a meter, which is a little more than a yard (3 feet) in U.S. terms. It is the largest bat in Africa.
For those of you who do not know sh*t about bats (or about bat sh*t, which can be used as fertilizer), the largest bats are always fruit-eaters. The hammer-head, however, has been known to prey on small animals. This is rare, but not unheard of.
That skull could've fooled me. A bite from that looks nasty!
Like the prairie chickens mentioned in a previous entry, hammer-headed bats are often cited as an example of lek mating. Males vocalize and flap their wings in order to attract a female. They are highly polygamous; only 6-8% of hammer-headed males may contribute to a hammer-head population.
Although it's unlikely that the Jersey Devil is really just an escaped fruit bat, the visual similarities are uncanny. Might there not have been an escaped fruit bat that someone thought was a demon baby (similar to escaped wild cats from private collections)? Granted, the creature would not have lived long; New Jersey is a very different environment from Africa. It's still an interesting idea.
