Question for any biology types out there:
What is the largest animal that has a population greater than man?
WAG:
The Norway rat or Black rat species.
Next down, probably mosquitoes (widening range), then cockroaches, ants and termites.
What say the rest of you?
I’ve heard a certain kind of shrimp is much more numerous than man. That would out-large all of those insects, but not the rats.
According to one Web site I just checked, the Guinness Book of World Records in 1989 listed domestic chickens as having a world population of 6.5 billion. If they are still more numerous than humans, they would outrank rats.
Among other birds, the Red-billed Quelea, a small African finch, is sometimes listed as having a world population of 10 billion, but usually only 1.5 billion.
Mosquitos are bigger than cockroaches? Remind me never to go to your cookouts.
